Abstract

Zigbee Network has potential applications in the field of automation, health care and industry. This network is WPAN based on IEEE 802.15.4 standard having low data rate, low complexity, low cost and low power consumption and long battery life. Zigbee network structure supports both fixed and mobile devices. So in order to achieve reliable and seamless connectivity, robust mobility management is very challenging because of limited size and capabilities of its constituent nodes. This network mainly investigates the effect of mobility on the performance un-interrupted data transfer. The performance evaluation has been done here for cluster tree and cluster mesh topologies in terms of standard QoS parameters like throughput, load and delay. Moreover the effect of mobility has been investigated by varying packet size.

Keywords

Cluster Tree, Cluster Mesh, Packet Size, Mobile Node, Speed.

Abstract

Network simulation is a popular methodology adopted for evaluating the performance of new protocols for wireless networks or for enhancing the already existing network protocols before implementing them in the real world. The main reason of adopting this methodology is the cost and complexity involved in actual implementation. Simulator comes for the rescue by providing a virtual environment of the network comprising of nodes and links between them without incurring high costs. Selection of an appropriate simulator that suits one’s needs requires complete knowledge about them .This paper can aid the researchers in the selection of a simulator as per their requirements.

Abstract

Wireless Sensor Network is the process of spreading of data among all the sensor nodes known as broadcasting and collection of data through the sensor nodes i.e. convergecasting. Convergecasting is followed by broadcasting in every application. In WSN energy efficiency is the main concern for which, large number of efficient routing protocols have been designed. This paper simulate the effect of RFI i.e. route flood interval (time when sink node send route establishment packet to all other sensor nodes) on back-off duration. This paper represents the simulation results of convergecast routing and various issues in this routing protocol.

Keywords

Backoff, Convergecast Routing, OMNET++ Simulator, Routing Protocols, RFI and Wireless Sensor Network.

Abstract

Self organizing networks are a promising technology to cater the needs of the future wireless networks and ad-hoc networks are one of the reliable and effective networks. Therefore, ad-hoc network is local area computer network (LAN) in which the individual network nodes forward packets to and from each other. A mobile ad hoc network (MANET) is made of wireless nodes which act as personal digital assistant .There is no centralized architecture control between the communicating nodes. MANET is a self configurable, reliable and self organized network where the mobile nodes move in any direction and the mobile nodes can receive as well as forward packets as a router. So, in this paper, a survey has done on proactive routing protocols and reactive routing protocol and performance is evaluated by comparing two routing protocols DSDV and AODV. For simulations NS-2 have used and generation of packets, end to end delay and throughput is evaluated of these protocols.

Keywords

MANET, DSDV, AODV, Throughput.

Abstract

Emerging needs of very high data rate have developed for short distance transmissions in recent times. In applications such as wireless monitor, radio diagnosis etc high data rate with low power consumption is needed for efficient working. Ultrawideband (UWB) has been identified as the key technology to achieve high data rates of around 500Mbps. Federal Communications Commission has allotted a 3.1– 10.6 GHz spectrum for UWB. For efficient and effective transmission at such high frequencies suitable antennas are needed. Thus there is a challenge to design such antennas that can work on UWB range. Microstrip patch antenna design has been widely used in UWB as found in the literature survey. In this work, such design efforts by various researchers have been reviewed. On the basis of shape of patch used, obtained observations are tabulated. It has been found that with the optimization of previously proposed designs, application oriented amendments can be achieved. There is a tradeoff between different parameters of antenna such as its size, bandwidth coverage, gain and losses. Different applications on the basis of features that the antenna offers have been highlighted.

Keywords

Antenna, Microstrip, Patch, Ultrawideband.

Abstract

Wavelength division multiplexing has become a preferred transmission technology in the transport network of long distance communication. In this paper a WDM system has been designed at different data rate(8*10,12*10,16*10) and compared using different data fiber standards(SMF,ALCATEL,ITUG.653) The designed system is evaluated to  find maximum transmission distance at(80,120,160)Gbps. It has been evaluated that ITUG.653 gives ideal performance with Q Factor of 15 and an acceptable bit error rate of 10^-54 at a distance of 313km with compensation among all fibre. The total of (8,12,16) channels at a data rate of 10Gbps with equal channel spacing of 300 GHZ and with different fiber standards has been evaluated.

Abstract

The emergence of DSRC 802.11p in VANET (Vehicular Adhoc Network) has resulted in the evolution of Intelligent Transport System (ITS). However, one of the major challenges in the success of VANET is the robust and reliable implementation through rapid vehicle movement and hostile channel conditions. Mobile IP can be considered as one of the most promising technologies to address the challenge of uninterrupted services in spite of rapid movement. In this work, a Mobile IP enabled scenario has been proposed and the hostile channel conditions have been modeled using Rayleigh fading distribution. The optimum QoS bounds have been obtained through extensive simulations by varying the queue size and application traffic type. Due to the quick handoff in Mobile IP, there is crucial need of selection of appropriate queue size responsible for accommodating data packets. Considering all these factors, this paper emphasizes on the selection of most suitable application traffic along with appropriate queue size even under realistic channel conditions for Mobile IP enabled City Scenario.

Abstract

Cross-Layer Design have now developing hottest research area in wireless sensor systems as it is pursuing to improve the ability of wireless networks remarkably through the joint optimization of several layers in the network. The design of our protocol is to deal with the overhearing problem and low duty cycle based on adaptive sleeping. The Mac layer is using the information of routing layer to decide the node duty cycle in order to extend the node's sleep time. Thus cross layer protocol design objective is to reduce protocol overhead significantly for route discovery as ring based structure find shortest path for the node in the outer ring to the sink in the network. Extensive simulation results shows that ring based protocol EEIMRP as compared to IMRP can significantly reduce the protocol overhead thus reduces delay in the network, improves energy efficiency, throughput and prolonged network lifetime.
