Abstract

Problem statement: In most of the existing works either detection of congestion or scheme for congestion control in wireless sensor networks are presented. A very few works have been done, taken in to account of both congestion detection and congestion control. In most of the congestion detection works they have not achieved accuracy in detecting congestion and have resulted with high latency time. Approach: In this study, we propose to design a multi-path energy efficient congestion control scheme to reduce the packet loss due to congestion. In our congestion detection approach, we follow a combined congestion estimation technique taking in to account on three main parameters specifically queue size, contention and traffic rate. For the congestion control, we design a rate control technique and a multipath routing protocol. Results and Conclusion: Simulation results show that our proposed approach achieves better throughput and packet delivery ratio with reduced delay, packet drop and energy.

Highlights

Wireless sensor networks: A Wireless Sensor Network (WSN) is a network composed of distributed autonomous devices using sensors to cooperatively monitor physical or environmental conditions such as temperature, sound, vibration, pressure, motion or pollutants at different locations
WSNs have a wide range of applications in object tracking, object localization, habitat observation, health monitoring and battlefield sensing among others (Sheu et al, 2009)
WSNs have inherent and unique characteristics compared with traditional networks

Summary

INTRODUCTION

Wireless sensor networks: A Wireless Sensor Network (WSN) is a network composed of distributed autonomous devices using sensors to cooperatively monitor physical or environmental conditions such as temperature, sound, vibration, pressure, motion or pollutants at different locations. Li et al (2011) have proposed a multipath energy- CONSEQ is executed in a hop-by-hop manner, it offers efficient routing protocol for wireless sensor quick reaction to potential congestion, but incurring little considering wireless interference In this techique, the nodes that are in discovered path of the interference zone are marked. Congestion Control (PCCP) for Wireless Sensor Networks (WSNs) Their technique makes use of crosslayer optimization and hop by hop approach for congestion control and the packet forwarding rate at intermediate nodes which is dependent on MAC protocol. For multipath routing, they employ a scheduling algorithm.
