“…The researchers in [21], suggested a novel method that uses the DSR routing cache to enhance the routing between mobile nodes in order to decrease the result of mobility in link transmission, which might help to overcome the link broken crisis. This technique updates the DSR's route cache by using proactive cache replace rather than an adaptive timeout mechanism in a link cache structure to delay a stale route in a session.…”

Current efforts for providing an efficient dynamic source routing protocol (DSR) for use in multi-hop ad-hoc wireless are promising. This is since DSR has a unique characteristic in that it uses source routing, instead of relying on the routing table at each intermediate device. This study addresses the current challenges facing DSR protocol in terms of the dynamic changes of the route and how to update such changes into the route cache of the DSR. The challenges typically persist when a sudden route break occurs resulting in a delay in updating the new node location into the cache of the DSR protocol. For that, this study proposes a novel algorithm to improve the cache updating of DSR protocol in the ad-hoc network using dominating set-based routing (DBR). In DBR, the dominating nodes establish node update cache in accordance with the characteristics of the new route. Network Simulator version 2 (NS2) was used to implement and evaluate the proposed algorithm. A comparison of certain performance metrics was carried among the proposed DSR-DBR, DSR-route-cache, and DSR-original in the transmission control protocol and user datagram protocol. The DSR-DBR performance result showed a significant improvement in the average throughput, average end-to-end delay, average discovery time and routing overhead.

“…Results were evaluated using both the TCP and UDP protocols. For DSR-DBR, two prior studies were compared: DSR-ROUTE-CACHE [21] and the original DSR. Using the three approaches, we ran the comparison with relation to the speed of the nodes.…”

“…The devices in MANETs have the freedom to move randomly in all directions, which play the roles of both the client and router together during sending or receiving the data in the network, where it must depend on in its own information to take the decisions to choose the paths which lead to the destination, which that create the challenges on finding and updating that information constantly (Ayoob, Sulaiman, Mohammed, & Abdulsahib, 2014).…”

“…The (Ayoob et al, 2014) presented new proposal in order to mitigate the negative effects resulting from the continuous mobility of the nodes and lasting change in the network topology. The proposal includes providing a new algorithm consist of two mechanisms (route status checker, route order) and make a change to the mechanism of keeping the routes in the cache memory by setting up two tables (Master route cache and Index Route Cache).…”

Mobile Ad-hoc networks (MANETs) involved in many applications, whether commercial or military because of their characteristics that do not depend on the infrastructure as well as the freedom movement of their elements, but in return has caused this random mobility of the nodes many of the challenges, where the routing is considered one of these challenges. There are many types of routing protocols that operate within MANET networks, which responsible for finding paths between the source and destination nodes with the modernization of these paths which are constantly changing due to the dynamic topology of the network stemming from the constant random movement of the nodes. The DSR (Dynamic Source Routing) routing protocol algorithm is one of these routing protocols which consist of two main stages; route discovery and maintenance, where the route discovery algorithm operates based on blind flooding of request messages. blind flooding is considered as the most well known broadcasting mechanism, it is inefficient in terms of communication and resource utilization, which causing increasing the probability of collisions, repeating send several copies of the same message, as well as increasing the delay. Hence, a new mechanism in route discovery stage and in caching the routes in DSR algorithm according to the node's location in the network and the direction of the broadcast is proposed for better performance especially in terms of delay as well as redundant packets rate. The implementation of proposed algorithms showed positive results in terms of delay, overhead, and improve the performance of MANETs in general.
