Abstract—There has been a massive growth in wireless communications in recent years. Many wireless communication techniques are commercially available like Wireless LAN, Bluetooth, and GSM to name a few. Access to the Internet via wireless communication devices has become an important issue due to the trend of an all-IP network in the 4G wireless networks. One such wireless technology gaining popularity is Wireless Mobile ad hoc Network, which is an infrastructure-less, autonomous, stand alone and self organizing network. It can be simply and flexibly deployed in almost any environment. However it has limited wireless coverage and limited connectivity. Mobile IP and IP micro-mobility protocols enable the mobile host to access Internet and change points of attachment without losing the connection. With the integration of MANET routing protocol and IP protocol, Internet connectivity to the MANET nodes can be achieved. Solutions to the integration problem, introduce an intermediate entity with hybrid mechanisms enabling it to connect to two different networks.
In this paper, an extended DSDV protocol, named as Efficient DSDV (Eff-DSDV) protocol has been used to provide bidirectional connectivity between ad hoc nodes and the hosts in the Infrastructure-based networks. The proposed framework uses one of the ad hoc hosts known as Mobile Internet Gateway (MIG) to act as a bridge between the two networks. The detailed performance comparison has been made between the proposed approach using Eff-DSDV routing protocol and then using the regular DSDV protocol. The simulation results not only show that the performance of the proposed strategy using Eff-DSDV is superior to using DSDV but also it is better than other integration strategies.
