Device-to-device communication is a cellular network communication technique in which cellular user devices directly communicate with each other without a base station. In the present work, resource sharing methods of device device users and cellular users are examined in terms of channel capacity gain. For this purpose, the problem of determining the transmit power values that provide the best data...
In order to extend the lifetime of a wireless sensor network, the energy consumption of individual sensor nodes need to be minimized. This can be achieved by minimizing the idle listening time with duty cycling mechanism and/or minimizing the number of communications per node. The nodes will have different relay loads for different routing strategies: therefore, the routing problem is important factor...
In wireless sensor networks, one of the key challenge is to achieve minimum energy consumption in order to maximize network lifetime. In fact, lifetime depends on many parameters: the topology of the sensor network, the data aggregation regime in the network, the channel access schemes, the routing protocols, and the energy model for transmission. In this paper, we tackle the routing challenge for...
