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

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.
