    Route discovery process is a major mechanism in the most routing protocols in Mobile Ad Hoc Network (MANET). Routing overhead is one of the problems caused by broadcasting the route discovery packet. To reduce the routing overhead, the location-based routing schemes have been proposed. In this paper, we propose our scheme called Location-based Routing scheme with Adaptive Request Zone (LoRAReZ). In LoRAReZ scheme, the size of expected zone is set adaptively depending on the dis-tance between source and destination nodes. Computer simulation has been conducted to show the effectiveness of our propose scheme. We evalu-ate the performances of LoRAReZ scheme in the terms of packet delivery fraction (PDF), routing overhead, average end-to-end delay, throughput, packet collision, average hop count, average route setup time, and power consumption. We compare those performance metrics with those of Lo-cation Aided Routing (LAR) and Location Aware Routing Protocol with Dynamic Adaptation of Request Zone (LARDAR) protocols. The simula-tion results show that LoRAReZ can provide all the better performances among those of LAR and LARDAR schemes. © 2013 The Institute of Electronics, Information and Communication Engineers.

    All mobile nodes participating in a group communicate with one another in the group through a shared radio link without cable or backbone composes an infrastructureless network, called Mobile Ad hoc Network (MANET). Because network topology may be changed at any time as result of mobility of nodes and the failure of available routes, Quality-ofService (QoS) of real-time multimedia application may have difficulty in satisfying their services. In this paper, we propose a routing scheme for multimedia services called Modified Dynamic Source Routing (MDSR) protocol. The MDSR selects the shortest path by using power level. Our proposed scheme provides lower average delay and mean number of hop path from source to destination than DSR protocol can provide. © 2006 IEEE.

    All communications in a network made by mobile hosts through a shared radio link without cable or backbone, commonly called Mobile Ad hoc Network (MANET). Since the network topology may change constantly because of mobility of nodes and the available routes may fail many times, Quality-of-Service (QoS) of real-time multimedia application may have difficulty in satisfying their services. In this paper, we propose a Routing Scheme for Multimedia Services, which selects the shortest path by using power level Our proposed scheme provides not only the lower means number of hops path from source node to destination node, but also higher thoughput than the conventional scheme. © 2005 IEEE.
