M. Jayekumar, V. Nagarajan · 2017
Wireless Sensor Network applications supporting diverse fields have gained a vital focus and interest from the researchers these days. WSN applications are designed to support scalable real time environment monitoring that depends on region of implication. The major challenges in WSN include energy optimization, routing, obstacle identification, security, etc. These constraints need prioritized optimization in fulfilling the requirements of the deployed environment. Many research approaches provide solutions for each of the influencing factors in WSN. We intend to survey the energy optimization techniques in WSN with distinct considerations. This paper focuses in surveying preceding optimization techniques under multi-objective perspective that results in tradeoffs. We exclude the familiar optimization approaches and analyze distinct metric specific optimizations based on link failure, load balancing and distance.
