The Wireless Body Area Sensor Networks and Routing Strategies: Nomenclature and Review of Literature

WBASN is an effective solution that has been proposed in terms of improving the solutions and there are varied benefits that have been achieved from the usage of WBASN solutions in communication, healthcare domain. From the review of stats on rising number of wireless devices and solutions that are coming up which is embraced by the people as wearable devices, implants for medical diagnostic solutions, etc. reflect upon the growing demand for effective models. However, the challenge is about effective performance of such solutions with optimal efficiency. Due to certain intrinsic factors like numerous standards that are available, and also due to the necessity for identifying the best solutions that are based on application requirements. Some of the key issues that have to be considered in the process of WBASN are about the impacts that are taking place from the wireless medium, the lifetime of batteries in the WBASN devices and the other significant condition like the coexistence of the systems among varied other wireless networks that are constituted in the proximity. In this study, scores of models that has been proposed pertaining to MAC protocols for WBASN solutions has been reviewed to understand the efficacy of the existing systems, and a scope for process improvement has been explored for conducting in detail research and developing a solution

Biocomm - A Cross-Layer Medium Access Control (Mac) And Routing Protocol Co-Design For Biomedical Sensor Networks

One of the most novel applications of wireless sensor networks in recent years has been in the field of biomedical research. Biomedical sensor networks are formed by tiny wireless sensor nodes, embedded inside the body. The communication protocol used in such networks must prevent the formation of hotspots in the network and at the same time route data efficiently, while conserving energy. In this paper we propose a cross-layer medium access control (MAC) protocol and routing protocol co-design for biomedical sensor networks. The cross-layer interactions among the network and MAC layers help optimise the overall performance of the in vivo network. Extensive simulations have been done to show that the proposed Biocomm protocol performs much better than the other existing MAC and routing protocols in terms of preventing the formation of hotspots, reducing energy consumption of nodes and preventing network congestion when used in an in vivo network. A variation of Biocomm, Biocomm-D has been proposed for delay-sensitive biomedical sensor network applications
