In wireless sensor networks, the overlapped sub-regions (faces) are generated due to the intersections among the sensing ranges of nodes. The faces play a significant role in solving the three problems k-coverage (i.e., all the points in the interested field should be covered by at least k active nodes while maintaining connectivity between all active nodes), coverage scheduling and cover sets. To...
The security is a critical issue in wireless sensor networks (WSNs). A complex form of Denial of Service attack type is collaborative black hole attacks which challenge the security of wireless sensor networks. The purpose of this attack is to receive and drop all packets. Wireless sensor network nodes have limited energy and also have limited processing capability. WSNs devices have limited resources...
