Abstract. A current challenge in wireless sensor networks is the positioning of sensor nodes for indoor environments without dedicated hardware. Especially in this domain, many app...
Most sensor network applications require quality of service guarantees on a network-wide basis, suggesting the need for global network cost optimization. The dynamic and nonunifor...
Due to limited energy capacity of batteries, the function lifetime of sensor networks in general is longer than the operational lifetime of single nodes. Therefore, to keep the ne...
In this paper, a new strategy is proposed to defend against colluding malicious nodes in a sensor network. The new strategy is based on a new relaxation labeling algorithm to class...

In this paper, we proposed a MAC protocol, which can dynamically adjust Listening/Sleeping time rate of wireless sensor nodes according to data traffic load. In sensor networks, se...
