Reduction in routing overhead in MANET using 2-ACK scheme and Novel routing Algorithm
Journal Title: INTERNATIONAL JOURNAL OF ENGINEERING TRENDS AND TECHNOLOGY - Year 2013, Vol 4, Issue 8
Abstract
Mobile Ad hoc Network (MANET) is a collection of mobile nodes equipped with both a wireless transmitter and a receiver that communicate with each other via bi-directional wireless links either directly or indirectly. In mobile ad hoc networks (MANETs), nodes usually cooperate and forward each other’s data packets in order to enable out-of-range communication. However, in friendly environments, some nodes may refuse to do so, either for saving their own energy or for intentionally disrupting regular communications (i.e. selfish or malicious nodes).This selfish nodes start refusing to forward or drop data packets thereby degrades the performance of the network. This type of misbehaviour is generally referred to as packet dropping attack or black hole attack, which is considered as one of the most critical attacks that leads to the network collapse. In this paper, we proposed the 2-ACK scheme which is used for detecting the selfish nodes, eliminating them and choosing the other path for transmitting the data. After choosing the other path for transmitting the data there is a huge routing overhead is generated. So, we use Novel Routing algorithm which helps in decreasing the routing overhead and makes the network stable. In MANETs, Novel routing algorithm will also check the confidentiality of data message.
