ISDV-Hop Localization Algorithm with Increased Node Density In Wireless Sensor Networks

A novel approach to the design of a localization algorithm for wireless sensor networks is presented, which promises scalability, with reduced energy consumption and localization error. The improved scalable distance vector hop (ISDV-Hop) algorithm employs the total least square trilateration method to achieve improved scalability, energy conservation and location accuracy. The algorithm could serve as a backbone of context aware wireless sensor network applications including, environmental monitoring and control of temperature and humidity for enclosures of internal horticultural enterprises, controlling potable and waste water, gas and electricity energy distribution systems and ground water collection and flood alerting systems for monitoring rainfall and accumulation points such as streams and rivers. Simulation results illustrate the operation benefits of the algorithm in terms of scalability, reduced energy consumption and improved location accuracy.
