In multi-cluster sensor network, the inter-cluster interference is a factor to bring packet loss and energy cost. In this paper, a slot pre-allocation algorism to deal with the inter-cluster interference in TDMA based sensor network is proposed. The algorism is totally based on TDMA MAC, without using frequency enlarged methods such as CDMA and FDMA, can be easily implemented and not demands additional...
Underwater wireless sensor network is often constrained by limited power, limited communication range and high bit error rate (BER). We focus on designing a TDMA service for a cube-based underwater wireless sensor network. Such network is readily found in many applications in the area of monitoring, hazard detection, and so on. In this paper, we propose an underwater self-stabilizing TDMA algorithm...
This paper presents a distributed algorithm for efficient Time Division Multiple Access (TDMA) slot allocation in Wireless Sensor Networks. Unlike most of the existent proposals, which try to guarantee interference-free allocation based on the n-hop criterion (which can only work with regular topologies), the presented algorithm bases its decisions on the received signal strength, allowing it to operate...
The design of medium access control (MAC) in wireless sensor networks (WSNs) poses several key factors such as energy conservation, bandwidth utilization, throughput, etc. This paper proposes a new MAC protocol referred to as DEE-MAC which reduces energy consumption by making the idle nodes sleep to reduce idle listening using synchronization at cluster heads. Each cluster is dynamically formed as...
