Obstacle Handling in Context-Aware Multilayer Hierarchical Protocol for Wireless Sensor Networks

Application diversities of Wireless Sensor Networks (WSN) emphasize on consideration of all potential factors including obstacle appearance. However, most reputed protocols of WSN has no or little concerned with this issue. In this paper, simple obstacle detection techniques and their solutions for context aware hierarchical protocols are proposed. These techniques enrich the functionality and deployment ability of the network to a next higher level. Performance evaluation shows effective conjunction of the proposed techniques with the example protocol and durable functionality during obstacle emergence period.
