Ant-colony-based Geographic and Energy Balance Routing for Sensor Networks

Recent advances in wireless sensor networks (WSNs) now witness the increased interest in the potential use in applications. Sensors are expected to be remotely deployed in large numbers and operate autonomously in unattended environments. In this paper, Ant-colony-based Geographic and Energy Balance Routing (AGEBR) was utilized to establish wireless sensor networks which had survival cycles. This Ant-colony-based routing can modify the geographic information based on the distribution characteristics of the ant colony algorithm, and finally achieve fast convergence and high efficiency. As a result, the sensor networks which did not have lasting energy supplement or only had limited energy complement could last a longer period without losing their sensing ability. Experimental results demonstrated that the proposed approach can keep balance of the network energy consumption, prolong the network lifetime, and enhance the successful sending rate without congestion.
