Hole Detection and Healing for Improving Coverage in WSNs

چکیده
A Wireless Sensor Network (WSN) consists of a large number of randomly deployed sensor nodes. These sensor nodes arrange themselves into a cooperative network and perform the three basic functions of sensing, computations and communications. Wireless sensor networks (WSNs) are increasingly being used to track objects and monitor various phenomena or region of interest (RoI), where the main task is sensing the environment and communicating this information to the base station. One of the major problems occurring in such environment is the formation of networks holes. Hole is the communication gap. Holes affect the general performance of the networks. In this paper, different hole detection and healing algorithms and methods for increasing the coverage in wireless sensor network is studied.

Hole Detection and Healing in Wireless Sensor Network
A wireless sensor network (WSN) is one of the fundamental services provided by the monitoring of a specific Region of Interest (RoI). WSNs due to holes in RoI exposure is unavoidable considering the fact that the inner nature, environmental factors, random Uses, and external attacks, is to ensure that revenue is covered completely and consistently Key. This paper seeks to issue mobile WSNs hole...

متن کاملReview over Hole Healing Techniques in Wireless Sensor Networks
Improving coverage and connectivity is a very important issue in wireless sensor networks. The unattended or uncovered region in a sensing field is called a coverage hole. A coverage hole impacts the performance of 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 priori...
متن کاملHoles Detection in Wireless Sensor Networks: A Survey
Now a day’s, it has been a great idea of research on using Wireless Sensor Networks (WSNs) to assist in the initial deployment of sensor nodes. Hole problem in WSNs is the most fundamental Problem in WSNs. Hole means a communication gap in WSNs. Finding an optimal sensor deployment strategy that would minimize the cost, reduce the node failure and also reduce the communication overhead. Then it...
متن کاملAn Efficient Distributed Coverage Hole Detection Protocol for Wireless Sensor Networks
In wireless sensor networks (WSNs), certain areas of the monitoring region may have coverage holes and serious coverage overlapping due to the random deployment of sensors. The failure of electronic components, software bugs and destructive agents could lead to the random death of the nodes. Sensors may be dead due to exhaustion of battery power, which may cause the network to be uncovered and ...
