Framework for monitoring and congestion control on Packet Dropping in Mobile Ad-hoc Network
Dr.Rohit Sharma, Himanshu Singh · International Journal of Engineering Trends and Technology · 2015
Packet Dropper nodes is a severe problem in MANET and they not only are harmful for the sender and receiver but they also lead to congestion in mobile ad-hoc networks as the sender may get involved in sending packets again and again as there is no acknowledgement from the receiver. Mobile ad hoc network is wireless network of mobile nodes, with no centralized management and control. Network congestion leads to reduced throughput, routing and lifespan, etc. of network packets. Dropping control packets may be beneficial for selfish nodes and malicious ones as well. For example, simply by dropping RREQ (Route Request) packets a selfish node could exclude itself from routes and thereby avoid receiving data packets to forward. Similarly, a malicious could drop RERR (Route Error) packets to keep the use of failed routes, potentially resulting in a denial of service.
