Network Coding in Wireless sensor Network - An Overview
ثبت نشده
چکیده
Network coding is a technique where each sensor nodes combine packets using mathematical operation, which reduces the number of broadcast packets in a wireless sensor network (WSN). Network coding methods are used to improve a network's throughput, efficiency and scalability when finding optimal solutions to the general network problems. It can also be a method for dealing with attacks and eavesdropping. However, the broadcast nature of WSN and the diversity of the links make network coding more attractive. In this paper, we survey the recent works on network coding, regarding their techniques, assumptions and applications in WSN.
