| Popis: | 94 The Mobile Ad hoc NETwork (MANET) is a kind of network without the existence of infrastructure. The mobile nodes (MNs) in the MANET can exchange their data packets directly with each others.. By adopting the routing protocols within the MANET, the MNs utilize the intermediate nodes to reroute their data packets and finally to the destination node. By using the ad hoc routing, the source node can conduct packet transmission to the destination node which can be outside of its transmission range. In general, the routing algorithms can be categorized into unicast and multicast routing protocols. The unicast routing protocols handle the situations that one source node is transmitting data packets to one destination node. The multicast routing protocols consider one source to multiple destination nodes for packet delivery. In most research work, only the hop counts within the transmission route are considered; while the influence from the receiving power and remaining energy of the MNs are neglected. This may results in insufficient energy remained within MN to successfully transmit the data packets. In this thesis, a Distributed Energy Routing Protocol (DER) is proposed for unicast routing of data packets. The proposed DER algorithm avoids adopting the low-energy intermediate node in the decision of the transmitting path and also provide the reliability for the transmitting packet. On the other hand, the Power-Controlled Hybrid Multicast Routing (PCHMR) protocol is proposed for multicast routing. It is composed of the advantages of the tree-based and the mesh-based routing protocols in order to provide more reliable network structure to transmit packets between multiple sources and destinations. In order to provide more reliable linkage on the path and to avoid the usage of an unreliable path, the proposed PCHMR protocol chooses the routing path according to the average received power of the MNs. The performance evaluation and comparison of the proposed DER and the PCHMR protocols will be conducted in simulations. |
