Abstract

Improving coverage and connectivity is a very important issue in wireless sensor networks. The unattendedor uncovered region in a sensing field is called a coverage hole. A coverage hole impacts the performanceof the wireless sensor network, disconnects the network topology and causes delay in data transmission.These coverage holes can be healed randomly or each hole can be assigned a priority value for healing. Inthis paper we will discuss about various hole healing strategies and their mechanisms.
