“…As hybird routing protocols are most suitable for the large scale network with high node density, the principle of the scenario design is to compare the whole With simulations of different number of nodes, we have proved that in random moving and big scale scenarios, C AHR performs better in end-to-end latency, routing overhead, throughput and packet delivery ratio [14] [15]. Figure 5 to figure 8 are the comparison results in the same scenario of two routing protocols.…”

Hybrid routing protocols in Ad Hoc networks com bine proactive routing protocols with on-demand routing proto cols and take advantages of both. However, the cost in delays and overheads resulted from simple domain formation algorithm of existing hybrid routing protocols is a main obstacle in improving the performance of overall ad hoc network. Owing to the above issues, in this paper we creatively apply the idea of clustering routing to hybrid routing protocols and propose a centralized adaptive hybrid routing protocol referred to as CAHR. In CAHR, several key nodes are selected using the centralized adaptive selection algorithm and different domains are formed according to the key nodes elected. By taking advantages of the key nodes, redundancy of routing forward is avoided, routing overheads are reduced and as a consequence, routing efficiency is improved.With simulations in OPNET Modeler of various scenarios, the superiority of CAHR is verified over traditional hybrid routing protocols in routing overheads, end-to-end latency, throughput and packet delivery rate.

This paper studies the fault management in mobile ad hoc networks. We focus on schemes which provide the robustness in MANETs: service restoration and service protection. Firstly, we propose an analytical comparison of service restoration, in terms of restoration time, at the routing layer (reactive and proactive protocols). Service restoration with reactive protocol is the most suitable in MANETs. The second motivation of the paper is an analytical study of the service protection at the network layer (multipath routing protocols) and its interest in terms of restoration time and reliability. The advantage of route redundancy in terms of restoration depends on the probability that alternate route is running after the primary route failure. The value, of this probability is studied, according to the used link connectivity maintenance mechanisms: Link-Layer Feedback Acknowledgements (LLF), Hello messages and Network-Layer Acknowledgements [1]. In terms of reliability, the multipath protocols are always better than unipath protocols. Segment recovery is the best recovery policy in terms of reliability.

“…And it is much more efficient than HELLO message sending, because it doesn't need any extra overhead. However, as a disadvantage, in paper [10] the author points that this mechanism is link layer protocol dependent. If the protocol of MAC layer is not IEEE 802.11, or is some another protocol without any ACK and RTS-CTS schemes, then it will not be practical.…”

The traditional routing protocols for mobile ad hoc networks (MANET) are not appropriate for wireless sensor networks (WSNs). The reason is the large amount of overhead produced may exhaust the energy of the network and shorten its lifetime, especially in the process of maintaining routes. In this paper, considering a large scale WSN, we propose a simple but efficient AODV-based protocol, called AODV with Route Identification and RREP Capturing (AODV-RIRC). With route identification the source nodes don't have to build a new route. And after capturing the RREP the intermediate nodes build routes to the destination silently. The simulation results verify its efficiency in dealing with events in a large scale WSN which consists of 1000 nodes at most. According to the results, AODV-RIRC reduces the control overhead significantly, saves more energy and shortens the route building time relative to the other two AODV-based protocols.
