“…COPE coding decisions are classified and improved thus making better coding decisions by K. Chi et.all [16]. In [17] the MORE and COPE principles have been joint in search of benefits of the two at the same time. Making routing aware of COPE coding opportunities has been investigated in [18] and [19], while [20] investigated new metric schemas for coding aware wireless routing.…”

This paper presents a novel, practical, routing-independent networkcoding algorithm: BON-Bearing opportunistic network coding. Simplicity is its main benefit as it introduces little overhead to the network since nodes do not need to keep track of received traffic for their neighbouring nodes. Algorithm makes coding decisions based solely on the information about the packet previous and next hop node position. Algorithm functions between the MAC and link layers, with small modifications made only to the MAC layer. Using different topologies and different traffic loads and distributions in the simulation model we evaluated algorithm performance and compared it to a well-known COPE algorithm.

Network coding is a technique where relay nodes mix packets using mathematical operations, which reduces the number of transmitted packets. Network coding was first proposed for wired networks to solve the bottleneck problem and to increase the throughput. However, the broadcast nature of wireless networks and the diversity of the links make network coding more attractive in wireless networks. Network coding can be classified as either inter or intra-session. Inter-session network coding allows the packets from different sessions (sources) to be mixed to solve the bottleneck problem. In contrast, intra-session network coding, which can be used to address the packet loss problem, uses the diversity of the wireless links and mixes packets from the same sessions. In this chapter, we survey the recent works on network coding in both general wireless networks and wireless sensor networks. We present various network coding techniques, their assumptions, applications, as well as an overview of the proposed methods.

“…Using multi-site data exchange as a vehicle, we examine coding gains that impact bottom line application performance. FlowCode allows us to derive gain from both inter-flow coding and the intra-flow coding made possible by coding over multiple packets in a generation, similar to a system proposed in I 2MIX [6] Other application-based network coding studies include [16], which concerns content distribution in multihop/mobile networks, and [17], which employs a cooperative content downloading application using mobile nodes.…”

“…In one example, COPE [5] extracts gain by buffering and opportunistically gathering information from neighbors about what coding opportunities might exist. Alternatively, I 2MIX [6] proposes to perform inter-flow coding by taking advantage of routes that encourage overhearing amongst intermediate nodes. In contrast, our system labels packets to identify flow direction and maximizes coding opportunities by using a layered network topology to balance traffic traveling away from a root layer with taffic moving toward the root layer.…”
