Accessing Internet by the mobile nodes in a vehicle on
the move, give rise network mobility (NEMO) for which IETF
has standardized NEMO Basic Support Protocol (NBSP).
However, NBSP suffers from sub-optimal route problem for both data and signaling packets, and as the nesting level increases, the problem worsens, resulting high handoff delay. High handoff delay also reduces bandwidth utilization per unit time. NBSP also suffers from late movement detection which disrupts the continuous service to the applications. To solve these issues, this paper proposes SLNEMO protocol that also reduces the cost of location update and remains mobility transparent to the nodes in the mobile network. Making the protocol mobility transparent also solves the problem of binding update storm. We utilize the hierarchical topology of a mobile network to reduce the cost of location update, and use buffering scheme to provide seamless handoff. Numerical results show that SLNEMO performs better
than ROTIO in terms of average handoff delay and packet loss
duration.
