They spend more energy during their traversal and can be conserved by minimizing the traversal. High degree of coverage is preferred in many applications. Energy conservation is one of the most demanded researches. MSNs with variable sensing range are best suitable in search-related operations. Degree of coverage can be increased whenever the situation demands. � 2014 Springer India.Book chapter
