CodeDrip: Data Dissemination Protocol with Network Coding for Wireless Sensor Networks
نویسندگان
چکیده
In this paper, we present CodeDrip, a data dissemination protocol for Wireless Sensor Networks. Dissemination is typically used to query nodes, send commands, and reconfigure the network. CodeDrip utilizes Network Coding to improve energy efficiency, reliability, and speed of dissemination. Network coding allows recovery of lost packets by combining the received packets thereby making dissemination robust to packet losses. While previous work in combining network coding and dissemination focused on bulk data dissemination, we optimize the design of CodeDrip for dissemination of small values. We perform extensive evaluation of CodeDrip on simulations and a large-scale testbed and compare against the implementations of Drip, DIP and DHV protocols. Results show that CodeDrip is faster, smaller and sends fewer messages than Drip, DHV and DIP protocols.

متن کاملAn Energy Efficient Clustering Method using Bat Algorithm and Mobile Sink in Wireless Sensor Networks
Wireless sensor networks (WSNs) consist of sensor nodes with limited energy. Energy efficiency is an important issue in WSNs as the sensor nodes are deployed in rugged and non-care areas and consume a lot of energy to send data to the central station or sink if they want to communicate directly with the sink. Recently, the IEEE 802.15.4 protocol is employed as a low-power, low-cost, and low rat...
