The inherently unreliable communication infrastructure compel WSN protocols to employ error control mechanisms. Traditionally, error control is achieved by a retransmission scheme using acknowledgment mechanisms. WSN architectures are severely resource constrained and the additional energy expense of transmitting error control messages can seriously degrade network lifetime. In this paper, we analyze...
Reliable transport protocols like TCP are in principle not well suited for wireless sensor networks (WSNs), due to both the characteristics of the network nodes (low computing power, strong energy constraints) and those of the typical applications running on such nodes (low data rates). Indeed, TCP has not been designed with energy efficiency in mind, and the end-to-end recovery of TCP makes it too...
