PROJECT TITLE :

Cooperative wireless sensor environments supporting body area networks

ABSTRACT :

Wireless Body Space Network (WBAN) in recent years have received vital attention, because of their potential for increasing potency in Healthcare monitoring. Typical sensors used for WBAN are low powered single transceiver devices utilizing a single channel for transmission at the Medium Access Control (MAC) layer. But, performance of these devices sometimes degrades when the density of sensors will increase. One approach to counter this performance degradation is to take advantage of multiple channels at the MAC layer, where optimal usage of the channels is achieved through cooperation between the sensor nodes. In this paper we propose a cooperative WBAN surroundings that supports multi-hop transmission through cooperation involving each environmental sensors and WBAN nodes. Our resolution extends the cooperation at the MAC layer to a cross-layered gradient based routing solution that allows interaction between WBAN and environmental sensors so as to make sure information delivery from WBANs to a far off gateway. In depth simulations for healthcare situations are performed to validate the cooperation at the MAC layer, still because the cross-layered gradient based routing. Comparisons to alternative cooperative multi-channel MAC and routing solutions have shown the overall performance improvement of the proposed approach evaluated in terms of packet loss, power consumption and delay.
