Analysis of Improved Path Selection Algorithm using PSO

In recent years, a broad research has been done in the domain of Mobile Ad-hoc Networks (MANETs). Due to the bounded resources in MANETs, to develop a reliable and efficient routing approach is still a threat or issues. There are distinct aspects appropriate for research like synchronization, power consumption, routing, bandwidth consideration, etc. This paper concentrates on routing approach which is the major challenging concern due to the change in topology of ad-hoc networks. Under a number of network scheme, such as network topology and size, it is difficult to figure out which routing protocol may perform well. In this paper we contribute an outline of broad range of the current routing approaches, with a special focus on their functionality and characteristics. Also based on the routing information and methodologies the comparison is provided, which can be used to make decisions of routing. Performance of all the routing protocols are considered as well. Further this consideration will benefit the researcher to get an outline of the existing protocols and advice which protocols may have better performance with respect to changing network scenario.
