Dynamic Source Routing (DSR) [4]. One of the most widely referred routing algorithms is Dynamic Source Routing (DSR), which is an on-demand routing algorithm and it has route discovery and route maintenance phases. Route discovery contains both route request message and route reply messages. In route discovery phase, when a node wishes to send a message, it rst broadcasts a route request packet to its neighbors. Every node within a broadcast range adds their node id to the route request packet and rebroadcasts. Eventually, one of the broadcast messages will reach either to the destination or to a node that has a recent route to the destination. Since each node maintains a route cache, it rst checks its cache for a route that matches the requested destination. Maintaining a route cache in every node reduces the overhead generated by a route discovery phase. If a route is found in the route cache, then the node will return a route reply message to the source node rather than forwarding the route request message further. The rst packet that reaches the destination node will have a complete route. DSR assumes that the path obtained is the shortest since it takes into consideration the rst packet to arrive at the destination node. A route reply packet is sent to the source that contains the complete route from source to destination. Thus, the source node knows its route to the destination node and can initiate the routing of the data packets. The source caches this route in its route cache.

In route maintenance phase, two types of packets are used, namely route error and acknowledgements. DSR ensures the validity of the existing routes based on the acknowledgments received from the neighboring nodes that data packets have been transmitted to the next hop. Acknowledgment packets also include passive acknowledgments as the node overhears the next hop neighbor is forwarding the packet along the route to the destination. A route error packet is generated when a node encounters a transmission problem, which means that a node has failed to receive an acknowledgment. This route error packet is sent to the source in order to initiate a new route discovery phase. Upon receiving the route error message, nodes remove the route entry that uses the broken link within their route caches. Ad Hoc On-Demand Distance Vector (AODV) [5]. AODV routing protocol is developed as an improvement to the Destination-Sequenced Distance-Vector (DSDV)

ALGORITHM 1. AODV Routing Protocol [5] // S is the source node; D is the destination node // RT = Routing Table S wants to communicate with D if RT of S contains a route to D S establishes communication with D else S creates a RREQ packet and broadcasts it to its neighbors // RREQ contains the destination Address(DestAddr), // Sequence Number (Seq) and Broadcast ID (BID) for all nodes N receiving RREQ if (RREQ was previously processed) discard duplicate RREQ end if if (N is D) send back a RREP packet to the node sending the RREQ else if (N has a route to D with SeqId >= RREQ.Seq) send back a RREP packet else record the node from which RREQ was received broadcast RREQ end if end for while (node N receives RREP) and (N != S) forward RREP on the reverse path store information about the node sending RREP in the RT end for S receives RREP S updates its RT based on the node sending the RREP S establishes communication with D end if

routing algorithm [6]. The aim of AODV is to reduce the number of broadcast messages sent throughout the network by discovering routes on-demand instead of keeping a complete up-to-date route information. A source node seeking to send a data packet to a destination node checks its route table to see if it has a valid route to the destination node. If a route exists, it simply forwards the packets to the next hop along the way to the destination. On the other hand, if there is no route in the table, the source node begins a route discovery process. It broadcasts a route request (RREQ) packet to its immediate neighbors, and those nodes broadcast further to their neighbors until the request reaches either an intermediate node with a route to the destination or the destination node itself. This route request packet contains the IP address of the source node, current sequence number, the IP address of the destination node, and the sequence number known last. Figure 5.2 denotes the forward and reverse path formation in the AODV protocol. An intermediate node can reply to the route request packet only if they have a destination sequence number that is greater than or equal to the number contained in the route request packet header. When the intermediate nodes forward route request packets to their neighbors, they record in their route tables the address of the neighbor from which the rst copy of the packet has come from. This recorded information is later used to construct the reverse path for the route reply (RREP) packet. If the same RREQ packets arrive later on, they are discarded. When the route reply packet arrives from the destination or the intermediate node, the nodes forward it along the established reverse
