A wireless network consisting of a large number of small sensors with low-power transceivers can be an effective tool for gathering data in a variety of environments. The data collected by each sensor is communicated through the network to a single processing center that uses all reported data to determine characteristics of the environment or detect an event. The communication or message passing...
In this paper, we propose and analyze a different channel allocation scheme in mobile cellular networks which not only gives priority to handoff calls but also tries to protect originating calls. We use channel reservation to protect handoff calls and in contrast, to protect originating calls, we set a maximum reservable channel, NG, in our scheme. In channel reservation schemes, there are some periods...
Since nodes in a sensor network have limited energy, prolonging the network lifetime and improving scalability become important. Therefore, the communication or message passing process must be designed to conserve the limited energy resources of the sensors. It is well known that clustering sensors into groups, so that sensors communicate information only to clusterheads and then the clusterheads...
