An increasing interest in supporting the nomadic nature of mobile nodes has lead to interesting ideas towards the deployment of Internet access to ad-hoc nodes. Most of the proposed solutions using mobile IP assume that the mobility agent is located adjacent to the ad-hoc domain. The current work differs from others in that it assumes a separation between the ad-hoc domain and the mobility agent. Mobile IP requires establishing layer-2 connectivity between the mobile device and the mobility agent to provide mobility support. This paper proposes using a gateway and a layer 2 tunneling protocol version 3 (L2TPv3) based tunnel between the ad-hoc domain and the mobility agent to provide Internet connectivity. The analysis of the proposed approach shows that it is more scalable with respect to other approaches.
