Medium access control schemes for flat mobile wireless sensor networks
One aspect of Mobile Wireless Sensor Networks (MWSNs) is the MAC protocol, which is critical in terms of reliability, delay and energy consumption. This work begins with a literature review, showing that the majority of MWSN MACs are designed for hierarchical architectures, demonstrating that there is a lack of MACs intended for flat architecture MWSNs. Subsequently, we propose three new MAC pr...
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 ...
