The research object of the thesis focuses on the load balancing routing algorithms and QoT aware routing in MANET. The research scope of the thesis is the DSR and AODV routing protocols.
The Dynamic Source Routing (DSR) protocol [13] is a typical example of the on-demand protocols, where each data packet carries in its header the complete ordered list of nodes the packet passes through. This is done by having each node maintain a route cache th[r]

6. Energy saving techniques at routing layer The problem of energy efficiency in MANETs can be addressed at different layers. In recent years, many researchers have focused on the optimization of energy consumption of mobile nodes, from different points[r]
When a node forwards a RREQ packet to its neighbors, it records in its routing tables the address of the neighbor node where the first copy of the RREQ was received. This fact helps nodes to establish a reverse path, which will be used to carry the response to the RREQ.[r]
− = + min{1 CBR i i , 1,2,... n 1} , where CBR i is the channel busy ratio that sensed by node N i . K. Xu, etc. (Xu, Tang et al., 2003) adopted this idea and added a smoothing factor to mask transient effects. But they only considered the AB estimation at each node within the path <[r]
Energy Efficient Load Balanced (EFLBAODV) and compared it to the traditionally existing reactive routing protocol Ad Hoc on Demand Distance Vector (AODV) thus using the load balancing technique to improve the node to node communication in our network. Also our routing protocol will be energy efficie[r]
The main method for evaluating the performance of MANETs is simulation. In this paper performance of Ad-hoc On-demand Distance Vector (AODV) reactive routing protocol is studied by considering IEEE 802.11 and IEEE 802.15.4 standards. Metrics like average end-to-end delay, packet delivery ratio, tota[r]

In this paper, we propose a novel secured compression algorithm for an ad hoc network in which the packets are encrypted and compressed. The decompression and decryption using the same algorithm happens by a perfect synchronization between the sender and the receiver. It is observed that the propose[r]
