Neighbors cooperation in WSN based on collective decisions

The paper describes the concept of neighborhood cooperation in context of the Wireless Sensor Network, in which each node can identify and communicate with neighbors around it. The innovative spatial routing scheme shapes an area where the packet retransmission toward the base station can take effect. In this work, the retransmission rules that use notion of actions limited to node´s neighborhood are determined. The proposed solution based on collective cooperation within neighborhood to support routing decisions was implemented and tested in Matlab environment. The simulation results show an improvement in the network adaptability to disturbances and as well as to changes of propagation conditions in the environment.
