We have proposed an architecture in which the MAC and routing protocols collaborate to discover routes and reserve resources, to organize nodes into clusters and to schedule the access to the transmission medium in a coordinated time-shared fashion.
The route discovery process in which the source tries to discover routes with high energy is based on SMR (split multipath routing)[29].
It in turn determines the efficiency of the protocol to discover routes successfully.
Proactive protocols maintain a list of all destinations and routes while reactive protocols discover routes on-demand when a packet needs to be forwarded.
Regarding the first set of simulations, Figure 14 shows the time needed to discover routes and assign weights, as well as the time needed to successfully negotiate all reservations as a function of node density (nodes per coverage area--n/CA).
If, during the route discovery phase, the cumulative robustness of the partially discovered route indicates a route failure probability surpassing this threshold, then the route request is not forwarded.
Route disruption and diversion attack: route disruption and diversion attack aims to prevent discovering route between two legitimate mesh routers or divert traffic to malicious mesh routers by modifying the mutable fields in routing messages.
Due to the time-varying nature of the route in MANET, the discovered route needs to be dynamically maintained for optimality in terms of traffic load, hop-distance, and resource usage.
Their on-demand robust routing algorithm selectively discovers routes that are probabilistically assured to survive for the duration of the underlying sessions or file transfers.
Gary Kemp of Spandau Ballet tweeted: "George Martin was the Edmund Hillary of music – adventurer, explorer, discovering routes for pop music we have all gratefully trod behind in", adding:.
