Energy-efficient even-parity network coding for adhoc networks

Thesis (M.S.)--Wichita State University, College of Engineering, Dept. of Electrical Engineering and Computer ScienceThe major difference between wired and wireless networks is their broadcast nature, specifically how transmitted data by one node may reach other nodes and vice-versa. This broadcast nature is a curse for wired networks but a blessing for wireless networks. Network coding is a technique where instead of just forwarding packets arrived at relay nodes, the node will collect several packets and then combine them together using an algebraic algorithm for transmissions. Network coding reduces the energy consumption by decreasing the number of transmissions required to communicate a given amount of information across the network. The aim of this thesis is to enhance network-coding strategy in order to improve energy gain, which in turn increases throughput in ad hoc networks. To that end, this thesis also proposes an even parity scheme that reduces processing time and power of nodes by improving coding opportunities. In addition, an even parity scheme allows for the coding of large numbers of packets at a time instead of coding just two packets using normal XOR operation
