Collisions and Congestions Detection and Management in Wireless Body Sensors: A Review

Abstract

Purpose -Congestion control is a very important area within wireless sensor networks (WSN). Congestions usually occur when traffic influx becomes greater than the aggregated or individual capacity of the transmitting channels. The constrained resources of the WSN must be considered while devising such techniques to achieve maximum throughput. This research reviewed existing algorithms to identify their strength and weaknesses.Method -The Researchers used a survey method to identify existing works and reviews on congestion management and control in Wireless sensor Networks this was done by identifying and categorizing various classes of congestion control.2228 Conclusion -This paper presents a review of most of the existing approaches and algorithms in addressing congestion. The benefits of addressing congestion are also discussed in this review paper. The paper also made suggestions for future study.Recommendation -Robust congestion checks should be implemented in wireless sensor networks to curb the level of packet drops thereby increasing network throughputs. Also, a hybrid algorithm that leverages the strengths of existing algorithms should be proposed and implemented.Practical Implication -This research will not only benefit academia, industries that implement wireless sensor networks, especially in healthcare will benefit tremendously from this research as the recommendations of this research will certainly aid the implementation of efficient and robust wireless networks.
