In order to be strongly connected in the network, a node may increase its power indiscriminately causing interference. Since interference is one of the major problems in wireless network, the proposed algorithm will co-operatively reduce inter-node interference in the network. Further, uni-directional links are a major source of interference as most of the routing protocol only utilizes bi-directional links. The algorithm will attempt to prevent such links or if required convert them into bi-directional links. The proposed algorithm is generic network layer power management algorithm and does not use special functionality of any routing protocol. Therefore, it can be applied to any routing protocol. Different routing protocols such as Dynamic Source Routing (DSR) in reference [3], Any Path Routing without Loops (APRL), Ad hoc On-Demand Distance Vector (AODV), On-demand Multicast Routing Protocol (ODMRP) and System- and Traffic- dependent Adaptive Routing Algorithm (STARA) in reference [4] have been used by the authors to prove their concept. To demonstrate the performance and the capability of the proposed algorithm, we have applied it to Optimized Link-State Routing (OLSR) protocol as an example of a typical routing protocol. We will show that the proposed algorithm provides strongly connected and more reliable network over dynamic physical channel modeled by log-distance path loss model, log-normal shadowing model and rayleigh fading model. It stabilizes node connectivity over the dynamic network and environment and even, to a certain extent, prevent node from being completely disconnected from the network. For the selected simulation environment, we will show that the proposed algorithm provides a shorter packet delay, improves the network throughput by as much as 37%, decreases the routing overhead and reduces interference.
