Load balancing parameters for geographic routing protocol in wireless sensor networks
Bijun Li, MinJung Baek, SeUng Hyeon, Ki‐Il Kim · 2010
Geographical routing protocol has been proposed to reduce the complexity of routing protocols, which are based on topology information in wireless/mobile networks. This kind of protocol is regarded as good working protocol in wireless sensor networks because reduced control overhead in geographic routing protocol is very suitable for each battery-powered sensor node. However, despite of several advantages, original greedy forwarding technique is very likely to cause different type of problems such as congestion. In this paper, we develop new parameters and apply existing possible parameters into original greedy forwarding in order to balance load efficiently. These parameters are derived from key characteristics of wireless sensor networks. Simulation results show that higher packet delivery ratio is achieved by proposed parameters in greedy forwarding.
