MANET is a temporary connection of mobile nodes via wireless links having no centralized base station. We developed a protocol with an enhanced route discovery mechanism that avoids the pre-transmission delay. When a source node wants to communicate with another node, it broadcast RREQ. EAODV give priority to the source node of real time transmission. When RREQ packet send to neighbor node, for...

This paper deals with power allocation strategies in a wireless personal area network (WPAN) supporting the IEEE 802.15.4 standard for low power transmission. The proposed transmission strategy for nodes belonging to a single primary route towards a destination is referred as Multihop Cooperative Transmission Chain (MCTC). The MCTC is based on the relays of the same message by multiple terminal...

In an event-based sensor network, a sequence of burst sensor data messages are required to be transmitted in shorter transmission delay without losses. However, it is difficult due to limited communication buffers in intermediate sensor nodes in a wireless multihop transmission route to the sink node. This paper proposes NeBuST-wide routing and transmission protocols in which sensor data messag...

Helicobacter pylori (H.pylori) is a gram-negative bacterium that has infected more than half of the world's population. This pathogen colonizes the human gastric mucosa and is usually acquired during childhood. It is an important cause of peptic ulcers, chronic gastritis and stomach cancer. Among the risk factors for acquisition of H. pylori infection, poor socioeconomic status, poor sanitizati...

We consider the problem of the optimal route selection in the presence of Rician fading channel. The variation in the signal strength due to fading is an overlooked fact in the wireless sensor networks. The conventional route selection strategies neglect the effect of fading and provide the low throughput routes for the data transmission. We consider the underlying dynamics of the wireless comm...

Sponsored by ARO MURI (ETX) [11], stimated transmission time (ETT) [6], etc. Usually, an intermediate node in the route receives a packet from the node immediately upstream and forwards it to the node immediately downstream. Hence the next-hop node for all packets is determined during the route discovery process. This selection of next-hop node in a route attempts to strike a balance between th...
