Routing Hole Handling Techniques for Wireless Sensor Networks: A Review
A Wireless Sensor Network consists of several tiny devices which have the capability to sense and compute the environmental phenomenon. These sensor nodes are deployed in remote areas without any physical protections. A Wireless Sensor Network can have various types of anomalies due to some random deployment of nodes, obstruction and physical destructions. These anomalies can diminish the sensi...
متن کاملCoverage Hole Detection in Wireless Sensor Networks
Wireless sensor network is the area where many researchers are focusing. The emerging technology of WSN is expected to provide a broad range of applications, such as battlefield surveillance, environmental monitoring and smart space and so on. Coverage is the important quality of service which is provided by the wireless sensor network. The coverage hole problem is a fundamental issue in WSN. T...
متن کاملTree-based coverage hole detection and healing method in wireless sensor networks
In wireless sensor networks, coverage is a fundamental issue affecting the quality of service. A coverage hole may appear anywhere in the area being monitored at any time because of many reasons. Thus, hole detection and healing have become major challenges towards achieving perfect coverage. This study provides a novel algorithm using trees and graph theory to detect and describe the existing ...
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 کاملBurstProbe: Debugging Time-Critical Data Delivery in Wireless Sensor Networks
In this paper we present BurstProbe, a new technique to accurately measure link burstiness in a wireless sensor network employed for time-critical data delivery. Measurement relies on shared probing slots that are embedded in the transmission schedule and used by nodes to assess link burstiness over time. The acquired link burstiness information can be stored in the node's ash memory and relied...
