Abstract:
A MANET is a collection of mobile nodes cooperating using low bandwidth wireless links. Its use is increasingly growing because it can be rapidly and easily deployed, and allows users to access and manipulate data anytime and anywhere. Because of these characteristics, classical routing protocols cannot be applied in such environment. To be efficient, routing protocols in MANET should in fact manage mobility, handle nodes energy dissipation and ensure security. Paradoxically, these constraints are not really taken into account. This paper presents a first step of our global objective towards the definition of a complete and generic security environment for MANET routing protocols. Its main contribution is then to propose a mobility-based clustering algorithm for MANET constituting the basis for our security architecture. From a given configuration of mobile nodes, we focus our attention on the definition of two major phases of the clustering process life cycle: (1) the setting up phase where clusters are generated and cluster-heads are elected and (2) the clusters maintenance phase where the organization of the clusters is maintained in the presence of mobility. This phase reacts to all network topology changes that may occur in the network such as the displacement of a node, the failure of a node, or the arrival of a new node. Simulation experiments are conducted to evaluate the performance of our algorithm in terms of the number of cluster-heads, the node lifetime and the packets delivery ratio.
