Multiple Metric Gateway Election in Heterogeneous MANETs
In tactical scenarios, different organizations form their own networks and use different protocols based on their specific objectives. This increases network diversity and makes interoperation more intricate. However, the interoperability of multiple tactical MANETs is an important issue when the MANETs are engaged in a common mission. In order to handle the diversity and interconnect different protocols the authors leverage a special type of node called gateway. The Gateway translates protocols and formats. It bridges any technology gaps and transparently interconnects multiple MANETs. Only a subset of the nodes qualifies for the Gateway role. Yet, it is not cost-effective to use them all simultaneously as gateways because they would generate excessive network overhead and might deplete the already scarce wireless network resources.
