Adaptive Dynamic Connectivity Hole Load-Balancing Geographic Routing in Wireless Sensor Network

To detecting connectivity failure around the wireless sensor network by using Adaptive Load-Balancing Algorithm (ALBA) for find the solution to identify the localization errors. Rainbow mechanism is used to differentiate grouping nodes using various colours. Both Adaptive Load-Balancing Algorithm and Rainbow mechanism are detects connectivity holes in network, a protocol for convergecasting in wireless sensor networks. ALBA-R features the cross-layer integration of geographic routing with contention-based MAC for relay selection and load balancing (ALBA), as well as a mechanism to detect and route around connectivity holes (Rainbow). ALBA and Rainbow (ALBA-R) together solve the problem of routing around a dead end without overhead-intensive techniques such as graph planarization and face routing. The protocol is localized and distributed, and adapts efficiently to varying traffic and node deployments. The ns2-based simulation, Hole Healing Algorithm is introduced for overcome these drawbacks in wireless sensor networks. The solution is dealing with connectivity holes, especially in critical traffic conditions and low-density networks.
