BEND-aware routing optimization in wireless mesh networks

Scope : A Lightweight Cryptographic Approach for Private Cope Data Coding

“…On the other hand, Re-encoding of a coded packet is agreed in DODEX+ (Distributed and Diffused Encoding with Multiple Encoders and Multiple Decoders) [13] to detect more codable flows. Besides that, some applications of linear programming to optimize the throughput of COPE [5] and BEND [3] to create more opportunities for coding and provide a better total network throughput. These issues have been addressed by considering the best paths which not only have more coding chances but also avoid wireless interference among network nodes in the network.…”

“…They can do this, since each of nodes can catch the its neighbours by overhearing their signals in the air. For example, N 3 . By XOR-ing P with its generated-and-sent packet P 3 and the overheard 1 = P + P 2 + P 3 + P 4 .…”

“…Nodes N 1 , N 2 , N 3 and can decode to obtain its expected packet. They can do this, since each of nodes can catch the 3 can overhear and the overheard wants to send packet P 6 to N 5 , then broadcasts P' to its receives and decodes P' to retrieve its expected packet…”
