On the reliability-aware geographic routing

Reliable communication is achieved when most reliable route is chosen from source to destination in ad hoc networks. The design of efficient routing protocols for dynamically changing network topologies is a crucial part of building power-efficient and scalable ad hoc wireless networks. If position information is available due to GPS or some kind of relative positioning technique, a promising approach is given by geographic routing algorithms, where each forwarding decision is based on the positions of current, destination, and possible candidate nodes in vicinity only. We focus on greedy routing algorithm and introduce a new hybrid metrics for selecting the next hop node in order to find most reliable route to the destination. We develop optimization models and provide simulation results for three new hybrid metrics.
