Intelligent mobile agents collaboration for the performance enhancement in wireless sensor networks

Abstract

Wireless sensor network consists of energy-dependent environment monitoring sensor nodes with sensing, computing, storing and communicating components with power unit. As the network is open to all other devices, incorporating security becomes a challenging task for the resource-constrained wireless sensor networks. Mobile agent's deployment provides solution to the problems occurring in WSNs. We define an intelligent mobile agent (IMA)-based security optimisation in which different agents govern the network performance such as routing, security check and transmission. Node's behaviour, available energy and congestion at the link are analysed for every transmission by different agents that ensure the secure communication by eliminating attackers from the routing path. Different from the other agent-based routing schemes, IMA utilises minimum agents for even a large scalable network. The process is simulated, and the results prove that IMA provides enhanced performance and secure communication.
