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 eave...
