Abstract:
The limited processing capabilities, low memory capacities and low data rate of sensor nodes in wireless sensor
networks, motivate the current researches study to focus on designing an energy efficient mechanism that can lengthen the
sensor nodes operational duration and relatively prolong the network lifetime while providing reliable data transmission.
In view of the fact that the sensor nodes in wireless sensor networks are typically irreplaceable, therefore, the protocols and
algorithms developed for sensor networks must incorporate energy consumption as the highest priority optimization goal.
An optimal route selection will provide higher throughput and reduction in delay from the end-to-end standpoint. Link
quality information can be extremely beneficial in this arrangement. The aim of this paper is to develop a routing algorithm
based on link quality estimator in mobile wireless sensor networks. This paper investigates most of the Link Quality Estimation
(LQE) approaches and identifies their strengths and weaknesses. It also investigates and identifies the limitations of some
LQE mechanisms utilized in current routing algorithms. As a result an existing routing algorithm namely RACE can be
enhanced based on suitable LQE approach named triangle metric, in terms of delivery ratio, loss ratio and energy consumption.
