Research On Energy-efficient Routing For Inter-community In Mobile Wireless Sensor Network

The mobile wireless sensor network is divided into non-connected areas due to the movement of nodes,energy consumption and other reasons,similar to the community in human society.At some point,the source node and the destination node may be in different communities can not communicate through the traditional wireless sensor network.Therefore,it is very meaningful to study the energy efficiency routing of mobile sensor networks.Aiming at the problem of selection of relay nodes in energy-efficient routing protocols for inter-community in mobile wireless sensor networks,a relay node selection routing algorithm ERAI based on forwarding capability and relay node selection protocol CLER based on social relation strength were proposed.The ERAI routing algorithm designs a new forwarding capability metric FC(Forwarding Capacity)based on the residual energy of nodes and the probability of encountering,and uses the incoming information and FC to realize the message transmission between communities.The CLER routing protocol adopts energy-aware mechanism as well as social relations,using the node and the community to meet the number of times and meet the time interval to quantify the social relationship SR(Social Relationship)between the node and the community,give priority to the remaining energy of the node,and then according to the value of SR to further select the relay node to implement the inter-community data transmission,and the BF algorithm was used to pass messages in the community.By comparing the ERAI and CLER routing algorithms with classical routing protocols in ONE simulation,the performance of the algorithm was compared from the life cycle of the network,the residual energy variance of the nodes,and the packet delivery rate,ERAI and CLER routing algorithm feasibility was verified.
