Thus to design a simple and high-efficiency routing protocol is an important issue. AODV routing protocol can resolve the routing problem of Mobile Ad Hoc Networks, but it still has many shortcomings, such that it uses flooding method to broadcast messages and finds the route, which cause heavy network overhead and other problems. In this paper, in order to resolve the low efficiency of simple flooding, we first analyze AODV routing protocol briefly. After that we propose an improved routing broadcast algorithm-GAODV, which aims to restrict the forwarding nodes within a local area through the geometrical routing, and prevent from flooding the control packet in the whole network. Simulation results show that the G-AODV effectively reduces network overhead and the end to end delay. Moreover, it also significantly improves the effectiveness of protocol and the overall performance of the network.10aAODV10aFlooding10aGeometrical routing10aMobile ad hoc network1 aSu, C.1 aZheng, L.1 aSi, X.1 aShang, F.  uhttp://www.scopus.com/inward/record.url?eid=2-s2.0-84866448629&partnerID=40&md5=1ddb21882f2996c7fdd5e7fbfd1511cb02040nas a2200229   4500008004100000245009800041210006900139260000900208300001400217490000600231520131100237653000901548653001301557653000801570653003601578653002701614653000801641100001401649700001601663700001401679856011701693       2010                        eng d00aAn AODV based QoS routing protocol for delay sensitive applications in mobile Ad Hoc networks0 aAODV based QoS routing protocol for delay sensitive applications  c2010  a303 - 3140 v83 aIn order to provide quality delivery to delay sensitive applications such as voice and video, it is extremely important that mobile Ad Hoc networks provide quality of service (QoS) support in terms of bandwidth and delay. Most existing routing protocols for mobile Ad Hoc networks (MANETs) are designed to search for the shortest path with minimum hop counts. However, the shortest routes do not always provide the best performance, especially when there are congested nodes along these routes. In this paper, we propose an on demand delay based quality of service routing protocol (AODV-D) to ensure that delay does not exceed a maximum value. First in this paper, we compare the performance of two prominent on demand routing protocols AODV and DSR in stressful situation. As the performance of AODV has been found better in our simulation than DSR, we decided to modify AODV routing protocol to provide quality-ofservice. This protocol takes into consideration MAC layer channel contention information and number of packets in the interface queue in addition to minimum hops. The protocol is implemented and simulated using GlomoSim simulator. Performance comparisons of the proposed AODV-D protocol against AODV, and QoS-AODV is presented and shown that the proposed protocol outperforms existing ones.10aAODV10aGloMoSim10aMAC10aMobile ad hoc networks (MANETs)10aPerformance evaluation10aQoS1 aKumar, R.1 aSarje, A.K.1 aMisra, M.  uhttp://www.scopus.com/inward/record.url?eid=2-s2.0-79960677246&partnerID=40&md5=b4b3c7a8accf3bb3de65c75a752e8915
