Mobile Ad hoc Network (MANET) is an autonomous, self-configuring and infrastructure-less system in which various mobile nodes are connected by wireless links. In MANETs hello messages are periodically exchanged to maintain the connectivity of neighbour nodes. While discovering neighbour nodes, an unnecessary hello message causes the problem of battery drainage in MANET routing protocols like AODV and DYMO. These ad-hoc types of networks are mainly used in the smart phones and origin the problem of energy utilization when neighbour nodes are discovered to maintain the connectivity. For the MANET scenario we take Random Waypoint Model and also the relationship between hello interval and event interval is considered. In this paper both the protocols are made adaptive and then Particle Swarm Optimization algorithm (PSO) is employed to give better results by reducing energy consumption and network overhead.

Brain Machine Interface (BMI) is a most important technological breakthrough in decades. In recent years, progress is being made towards sensory substitution devices for the blind. In the long run, there could be the possibility of brain implants. A brain implant or cortical implant provides visual input from a camera directly to the brain via electrodes in contact with the visual cortex at the backside of the head. In this paper, we proposed some applications where BMI can be used effectively which are very much useful for the society.
