Improvement of Medium Access Control Protocol to Reduce Latency in Ubiquitous Wireless Sensor Networks
In several ubiquitous sensor networks, sensor nodes often face contention for medium access and service. Unfortunately, traditional carrier sense multiple access with collision avoidance (CSMA/CA) protocols such as the IEEE 802.11 Distributed Coordination Function (DCF) do not handle such constraints adequately, and this weakness finally leads to an increase in the latency and degradation of th...
متن کاملAn Energy Efficient Medium Access Protocol for Wireless Sensor Networks
Wireless sensor networks have been widely used in many important fields such as target detection and tracking, environmental monitoring, industrial process monitoring etc. Since the nodes in wireless sensor networks consist of a limited power source, energy efficient operations of the nodes are very important. Although energy conservation in communication can be performed in different layers of...
متن کاملMedium access control in wireless sensor networks
Limited energy, computational, and communication resources complicate protocol design within sensor networks and prevent the application of many techniques used within other networks. Constraints on sensor node cost further restrict which technologies sensor networks may utilize. Despite much attention in recent years, researchers have yet to achieve the goal of long term, independent operation...
متن کاملMedium Access Control in Wireless Sensor Networks
This paper reviews medium access control (MAC), an enabling technology in wireless sensor networks. MAC protocols control how sensors access a shared radio channel to communicate with neighbors. Battery-powered wireless sensor networks with many nearby nodes challenge traditional MAC design. This paper discusses design trade-offs with an emphasis on energy efficiency. It classifies existing MAC...
متن کاملMulti-channel Medium Access Control Protocols for Wireless Sensor Networks: A Survey
Extensive researches on Wireless Sensor Networks (WSNs) have been performed and many techniques have been developed for the data link (MAC) layer. Most of them assume single-channel MAC protocols. In the usual dense deployment of the sensor networks, single-channel MAC protocols may be deficient because of radio collisions and limited bandwidth. Hence, using multiple channels can significantly ...
