topology updates. Furthermore, a node must conduct a reliable and

fast discovery procedure to determine which resources or services are

available on which nodes while moving around. To access a resource

and service shared by some nodes outside of its transmission range,

the node will rely on an efficient multihop routing mechanism to

reach the destination node.

1.3.3 Integration of Heterogeneous Wireless Networks

The aforementioned trend of convergence of computing and com-

munication faces a few challenges in the technological and business

domains. Heterogeneous network infrastructures have to coexist and

operate with each other to support internetwork roaming and hand-

off and must be transparent
