The effort dedicated to the ultimate goal of designing an architectural framework for tactical mobile ad hoc networks (MANETs) has long been hindered by the excessive control overhead of routing protocols to maintain a full view of the network topology. This paper explores the viability of adopting network coding as a means of improving reliable data delivery while lowering control overhead in large scale MANETs. Simulation results show that the proposed protocol, Network Coded STORM, achieves in excess of 95% packet delivery ratio and reduces the overall overhead by more than 50% in scalability experiments.

    • "Since link's ETX metric and Steiner tree are used in [8], it requires a lot of control overheads to maintain networ k connectivity. The authors in [9] apply network coding to reduce overall overheads in multicast data delivery. Then, a hierarchical network topology is used to deal with scalability issue in large scale mobile ad hoc networks. "

    ABSTRACT: Network coding is an emerging approach which is currently applied to wireless networks to improve network throughput and other performance. However, in mobile ad-hoc wireless networks, because of dynamic network topology, network coding may not improve network throughput if destination nodes fail to retrieve original packets due to lack of necessary information to decode coded packets. In this paper, we propose a Network Coding based Reliable Multicast Routing Protocol, called CRMP, in mobile ad-hoc wireless networks. Our proposed CRMP has the following novel features: i) it builds a stable mesh structure to improve coding and decoding opportunities, ii) it uses random linear network coding to simplify coding algorithm, iii) it has a local route repairing mechanism to prevent decoding failures caused by local route breaks. CRMP is especially well-suited for reliable, high speed multimedia applications. The performance of our proposed CRMP is evaluated via different scenarios. The results show that CRMP outperforms previously proposed multicast routing.

    ABSTRACT: In this paper, a Network Coding based Real-time Multicast (NCRM) protocol is proposed for real-time multicast services in Mobile Ad-hoc Networks (MANET). Through reducing the forwarding times for data packets in MANET, NCRM can not only decrease the energy consumption but also improve the throughput performance. To satisfy the maximum end-to-end delay deadline requirements for real-time services, NCRM adopts a mechanism with strict delay constraints. Simulation results show that, in those real-time multicast scenarios with many receivers and/or high node motilities, NCRM outperforms those traditional protocols such as PUMA and MAODV in terms of transmission reliability and energy consumption significantly.

    ABSTRACT: This paper presents a flexible inductive coil tag for sensing the electric current in the two-wire power cords of household goods. The tag is fabricated using a complementary metal-oxide semiconductor compatible SU-8 flexible technology which provides unique device characteristics of low-cost, reliability and pervasiveness. With a 30-turns coil design in an area of 0.5$\,\times\,$1 ${\rm cm}^{2}$, the coil tag can provide sensitivity of 18 and 21 $\mu{\rm V}/{\rm A}$ for detecting 50-and 60-Hz electric current in the ampere regime, respectively.
