TDMA is probably the best choice for an energy efficient multiple access protocol for wireless sensor networks. As such there exist many approaches of increased complexity, using different algorithms and combining information from other layers or multiple access techniques. There are many surveys detailing the protocols and their advantages and disadvantages, but we feel that they don't give a general...
Data memory has been a very scarce resource in sensor networks. Thus, its efficient utilization is necessary. There cannot exist a memory allocator that will deliver best performance and least memory consumption for all programs, but a particular allocator that works best for a particular program is possible. In this paper we present SDMA, a simulation-driven dynamic memory allocator for wireless...
A typical wireless sensor network (WSN) operates under the harsh constraints of limited power resources, which poses challenging problems in its network design process. As a result, the energy consumption characteristics of the WSN need to be precisely studied across different layers of the communication protocol stack. In this paper, we present a thorough investigation on the energy consumption of...
Wireless sensor network has been widely used in many types of monitoring application in these recent years. For monitoring application such as forest or building monitoring, sensor nodes equipped with temperature sensor, smoke detector and camera will trigger immediately when a fire breaks out. Due to those sensor nodes are transmitting the sensor packets to a sink node at the same time and without...
In this paper, upper and lower bound on the transmission capacity of underwater sensor networks are derived. Transmission capacity is defined as the maximum permissible density of simultaneous transmissions that allows a certain probability of successful reception. In order to drive these bounds it is assumed for the network model that the distance between source and destination is a fixed value....
