Abstract

The complexity of cellular radio networks yields new demands concerning network security. Particularly the task of detecting, repulsing and preventing abuse both by in- and outsiders becomes more and more difficult. Wireless mobile grids are one of the emerging grid types, which help to pool the resources of several willing and cooperative mobile devices to resolve a computationally intensive task. The mobile grids exhibit stronger challenges like mobility management of devices, providing transparent access to grid resources, task management and handling of limited resources so that resources are shared efficiently. The execution of the task on these devices should not be affected by their mobility.

The proposed work presents performance evaluation of wireless mobile grid using normal walk mobility model. The normal walk model represents daily motion of users and the direction of motion is mostly symmetric in a real life environment; thus it is effective in location updating of a mobile station and in turn helps task distribution among these available mobile stations. Some of the performance parameters such as Task Execution Time, task failure rate, communication overhead on Brokering Server and Monitoring Cost are discussed.

Abstract

Reliability and Availability are very important factors for wired/wireless networks. Because of advances in Internet, there is a huge demand for reliable (99.999%) network. Now a day’s Ipv4 address pool is exhausted so implementing IPv6 has become must. Implementing directly the advanced network infrastructure overnight is highly impossible and not so economic. So lot transition mechanisms are proposed by IETF to move on for next generation computer network gradually, which is more economic and effective. Today most of the organizations implemented reliable network by implementing many router redundant protocols such as FHRP, GLBP and HSRP. In this paper, our attempt is to have IPv6 based Infrastructure for Medium and Small enterprise network by simply configuring MTM mechanism with the above protocols to achieve reliable network. A concept of converting multihomed edge node to act as pointer, which implement/configure reliable connectivity with the transition mechanism for small and medium size enterprise network. Overall it’s our attempt to implement an economic and reliable next generation network.
