Centralized Router Election for IP-WSN Based on Facility Location Model
Zhen Hua Wu, Xiao Chuan Huang · Advanced materials research · 2012
It is a good alternative that uses reduced IPv6 as network layer protocol of wireless sensor network (WSN). This will generate a new problem: how to choose some nodes as router for homogenous, dense deployment WSN. This paper proposed a centralized router election method, which is based on facility location model, for IP-WSN. This method creates a 0-1 integer programming model by regarding router election as uncapacitated facility location problem firstly. Then genetic algorithm is used for solving the created model. The simulation results show that this method can elect small number of nodes as router with high efficiency.
