Wireless sensor networks consist of low power lightweight sensor nodes that are often placed remotely for applications like wildlife monitoring, rainforest monitoring, military surveillance, forest fire detection etc. Here energy is a critical issue as nodes cannot be recharged and/or replaced frequently. In this paper we propose an energy efficient hierarchical routing protocol for Wireless Sensor...
In this paper, we propose a solution for detecting and avoiding black hole attacks (both single and cooperative) and ensuring secure packet transmission along with efficient resource utilization of mobile hosts at the same time. According to our proposal, evaluation of trust of every node in the network is based on parameters such as stability of a node defined by its mobility and pause time, remaining...
