AN EFFICIENT AND ROBUST ACTIVE INFORMATION SHARING SCHEME FOR MOBILE ADHOC NETWORKS

Abstract

A Mobile Ad hoc Network (MANET) is a network of mobile devices, which are connected by wireless links. Its ability of being deployable in an infrastructure less scenario creates an interest among researchers and opens the scope for large number of applications. The characteristics like random mobility and dynamic wireless links between mobile nodes poses challenges for MANET application developer. Active Information Sharing Scheme is a scheme, which provides the capability of tactical information collaboration among the soldiers in the battlefield. The instantaneous information of battlefield has great importance for the military operations. As the information is shared by all soldiers so, it requires consistency among the updates that take place in the battlefield. This consistency should be maintained even in presence of faults. In this dissertation, a fault tolerance distributed mutual exclusion technique is proposed for MANETs. Extensive simulation is conducted, results shows that the proposed scheme is efficient and effective in various scenarios under different load conditions. Finally the thesis is concluded by pointing out some open issues and possible direction of future research relating to the distributed mutual exclusion problem in MANETs
