Reduction in information loss due to isolated and dumb nodes using ant colony optimization for WSN

A Wireless Sensor Network is a collection of miniature devices known as Sensors that are intended for the purpose of sensing and sending data and information to the sink. They are used in various applications and in areas that require continuous monitoring such as military fields and medical cabins. The most critical issue or the important criteria regarding this WSN is energy conservation and lifetime maintenance. Although various clustering and routing mechanisms are proposed for WSNs, the problem remains unsolved and still it remains as a popular research topic. One such idea to improve the lifetime improvement is the effective usage of the isolated and dumb nodes in the network. Dumb nodes are different from the isolated ones. The nodes that continue sensing but unable to send the data is categorized as dumb nodes while the nodes that aren’t included into clusters are called isolated nodes. We have proposed a method known as RILoID-ACO (Ant Colony Optimization enriched scheme for Reduction in information loss in the occurrence of Dumb and isolated nodes) that enables the practice of mobile mule in collecting the data from isolated and dumb nodes by enhancing a trust parameter. Success probability of 100% and data loss protection over 19% is obtained as the result of simulation that shows the success of the proposed system.
