Abstract
Two of the existing reliable transport layer protocols for wireless sensor networks- Distributed TCP Caching and Event To Sink Reliable Transport protocol, does not score well in terms of efficiency. Considering the total number of retransmissions as a QoS parameter for efficiency, our protocol k-RTP ( k Hop Reliable Transport Protocol ) is promising. In our protocol only the nodes do cache the packets and retransmit them in case of packet loss. The value of k is varied dynamically depending on the rate of packet loss in the network. In case of congestion occurring in the network at a particular node, the error rate increases which in turn results in a different value for k. Thus a new caching node is selected and this helps in reducing packet loss. Both the mathematical and initial simulation results are promising
