A Forwarding Game Approach for Reducing Topology Control Traffic in MANETs

摘要

With the advances of mobile ad hoc networks, reducing control traffic has become one of the most important fields that need to be addressed in different routing protocols. In such networks, where optimized link state routing (OLSR) is used as a routing protocol, each node broadcasts the topology control (TC) messages so as to share the network topology with other devices. Furthermore, and in order to optimize the TC overhead, OLSR uses a mechanism called multi-point relays (MPR) which is considered as the key functionality of this protocol. However, the redundant control packets will always exist and circulate across the network. In this paper, the key novelty is to propose a forwarding strategy for a robust minimization of the topology control traffic. The suggested solution is based on the forwarding game theoretic approach. Moreover, the proposal aims to control the duplicate transmission of TC messages forwarded by MPR nodes in order to improve the network overhead and energy consumption. Additionally, the simulation results using network simulator 3 are presented to confirm the effectiveness of the proposed solution.
