Connectivity and Coverage Maintenance in Wireless Sensor Networks

Free registration required

Executive Summary

One of the main design challenges for Wireless Sensor Networks (WSNs) is to obtain long system lifetime without sacrificing system original performance such as communication connectivity and sensing coverage. A large number of sensor nodes are deployed in redundant fashion in dense sensor networks, which lead to higher energy consumption. They propose a distributed framework for energy efficient connectivity and coverage maintenance in WSNs. In their framework, each sensor makes self-scheduling to separately control the states of RF and sensing unit based on dynamic coordinated reconstruction mechanism.
