—In this paper, we propose a new control method to cover “holes” in wireless sensor networks. Many applications often face the problem of holes when some sensor nodes are dis...
Energy efficiency is one of important issues in the resource contrained wireless sensor network. In this paper, we propose the authentication and key agreement protocol that effic...

Communication neighborhood in wireless sensor networks changes often as links break or appear. Therefore, monitoring link quality and (logical) network topology is necessary. As no...
In many applications of wireless sensor networks, sensor nodes are manually deployed in hostile environments where an attacker can disrupt the localization service and tamper with...
