A node will wait for the Additional Control Gap (ACG) period after exchanging the RTSCTS packet using the suggested protocol before starting the transmission of data packets. Other nodes in the area may plan simultaneous transmission at this ACG time by exchanging RTSCTS packets with one another. This technique of installing directional antennas to avoid interference while simultaneously ensuring simultaneous transmissions among nodes in the vicinity may enhance the overall throughput and latency of wireless ad hoc networks. The suggested MAC protocol, in combination with TCP, serves to lessen the possibility of medium congestion and collisions in multi-hop situations by scheduling simultaneous transmissions. After identifying the bottleneck node on the high-traffic route, the heavy-traffic route moved to a different dedicated path to facilitate longhop flow. This makes it feasible for longhop flow to use the completely available bandwidth of the recently allotted dedicated lane and ensures that traffic on the congested route will reduce. Additionally, the dissertation offers a simple but efficient hybrid model as a solution to the issues that could come up when carrying out disaster relief activities. According to the suggested concept, stationary SANET grid nodes that is installed will allow mobile MANET nodes that are more than 13 kilometres outside of the transmission range of the infrastructure network to connect to the internet and the central command. In the case of a disaster, this method increases the coverage area of MANET nodes, enabling those nodes to connect with and exchange data with the rescue and relief operations centre 2020 2020 08 18 10.54216/IJWAC.010201 https://www.americaspg.com/articleinfo/20/show/1403
