Review of unstructured architecture for voice and data services in mobile communication

In view of rapidly growing trend of mobile communication, there is tremendous demand for wireless technologies. Mobile communication networks are getting more and more complex with variety of services they offer, variety of devices connected to the network, variety of possible interconnections they have to make and network topology they use. As the number of mobile customers are increased, network has to provide services to all mobile customers. However, as the mobile devices moves between networks signaling overhead causes real time data traffic. Developing routing algorithms for mobile communication is a key challenge. In this paper we present a detail review of hybrid routing protocols for mobile communication. We consider both protocols (a)Proactive routing protocol which is based on periodic exchanges that updates the routing tables to all possible destinations, even if no traffic (b) Reactive routing protocol which is based on on-demand route discoveries that updates routing tables only for the destination that has traffic going through. There are two ways to enhance the performance of unstructured architecture for voice and data services in mobile communication. One way is to improve the algorithm for selecting path, second way to modify the routing algorithm by considering new characteristics for less signaling overhead.
