Study on low-consumption and secure GEAR routing protocol improved by trust evaluation
Rui Zhou · Computer Engineering and Applications Journal · 2011
To the problems of threat to routing security and limited energy of the nodes in GEAR,a new routing protocol named T-GEAR based on trust mechanism and data fusion is proposed.By adding trust parameters on each node,T-GEAR will take into account the node's trust value when selecting the next hop node.And this can avoid the next hop node is an attack node.Moreover,in the target area,this new protocol can aggregate the data to low the energy consumption to some degree.Simulation results show that T-GEAR has longer network lifetime,higher packet transmission rate and lower packet loss rate than GEAR protocol while attacking nodes exist.
