We propose to apply the concept of Cost-to-Progress Ratio (CPR) in greedy routing for load reduction and balancing. The load of a node is the percentage of time it is occupied by forwarding traffic or inability to forward due to interference. The resultant routing protocol, named CPR-routing, is a localized parameterless approach, optimizing the ratio of nodal load and geographic progress. Through...
Greedy forwarding is an efficient and scalable geographic routing algorithm for wireless networks. To guarantee the success of greedy forwarding, many research efforts assign virtual coordinates to nodes to obtain a greedy embedding of the network. Different from these existing efforts, this paper presents an approach that enables greedy forwarding to succeed in directional wireless networks by selecting...
Geographic routing is assumed to be the most potential routing scheme in wireless sensor networks (WSNs) due to its scalability and efficiency. Recently more and more research work about geographic routing pay attention to its application scenarios in duty-cycled WSNs because of the natural advantage of saving energy consumption with duty-cycling. However, it may cause significant latency issue when...
