Multicast Routing Algorithm

Wireless Multicast is one of the important problems with applications to opportunistic networks, such as delay-tolerant networks (DTNs), personal, pocket-switched networks (PSNs) etc. Network Coding has received many attentions because it improves potential network throughput and robustness by the way of combining multiple packets in the routers and reducing the transmissions. This paper combines network coding with opportunistic routing to improve the throughput of wireless multicast, where an Inter-coding and Intra-coding scheme is introduced to the traditional multicast routing algorithm (OR-DNC, Opportunistic Routing with Dual Network Coding). Compared with traditional multicast routing without coding and MORE-M, OR-DNC performs better in terms of throughput, transmission reduction and coding gain.

Maximal Capacity

Network coding can improve the optical multicast routing performance in terms of network throughput, bandwidth utilization, and traffic load balance. But network coding needs high encoding operations costs in all-optical WDM networks due to shortage of optical RAM. In the paper, the network coding operation is defined to evaluate the number of network coding operation cost in the paper. An optical multicast routing algorithm based on minimal number of network coding operations is proposed to improve the multicast capacity. Two heuristic criteria are designed to establish the multicast routing with low network coding cost and high multicast capacity. One is to select one path from the formerKshortest paths with the least probability of dropping the multicast maximal capacity. The other is to select the path with lowest potential coding operations with the highest link shared degree among the multiple wavelength disjoint paths cluster from source to each destination. Comparing with the other multicast routing based on network coding, simulation results show that the proposed multicast routing algorithm can effectively reduce the times of network coding operations, can improve the probability of reaching multicast maximal capacity, and can keep the less multicast routing link cost for optical WDM networks.

In this paper, an energy-efficient multicast routing algorithm in multi-hop wireless networks is proposed aiming at new generation wireless communications. Different from the previous methods, this paper targets maximizing the energy efficiency of networks. In order to get the optimal energy efficiency to build the network multicast route, our proposed method tries to maximize the network throughput and minimize the network energy consumption by exploiting network coding and sleeping scheme. Simulation results show that the proposed algorithm has better energy efficiency and performance improvements comparing with the existing methods.
