An energy efficient protocol exploiting cache data for sensor networks

Abstract

Minimizing energy consumption is important for prolonging the life of battery powered sensor nodes. A major portion of the power consumption is spent in communication with other nodes. If any communication fails, the message needs to be re-transmitted, resulting in added energy consumption. In this paper we suggest having a Failed Communication table, which keeps track of number of failed communications with each node in the group, while the nodes are updated with duplicate values for better resistance against loss of data. Consulting this table while selecting a path would help in detecting local interference and avoiding it while routing.
