One of the main problems in wireless sensor networks is the successful coverage of a number of targets lying on a field and at the same time the maximization of the lifetime of the network. Many algorithms have been proposed in the literature in order to find the maximum number of disjoint or non-disjoint sets of sensors (cover sets), where one set can be active at any one time. The complexity of...
Dynamic spectrum management (DSM) is a key feature for enhancing cooperation in wireless video sensor network (WVSN) towards supporting communication of high data-rate video information. Unlike traditional spectrum allocation, DSM in WVSN should have topology control and distributed control center. In this paper, we propose an ILST algorithm for constructing distributed DSM topology control with the...
Huge interest and demand on information superhighway have pressed various telecommunications research fronts and lead to a new form of future Internet consisting of wired and wireless segments where resource-constrained devices such as palm pilots and sensors may become integral parts of the Internet rather than access-only platforms. One of the key design problems is the security in such heterogeneous...
