	abstract = {In Wireless Sensor Networks (WSNs), sensing nodes
operate in dynamic environments resulting in neighboring nodes
being discovered or lost at any moment causing the network
topology to change constantly. Hence, routing schemes especially
geographical ones (which use node positions to route data
packets) require periodic exchange of control packets to discover
neighboring nodes. Even though it is intuitive that the overhead
caused by their periodic broadcasts may affect the end-to-end
performance of the routing scheme, previous works have not
thoroughly studied the impact of transmission power and frequency
of control packets in static as well as mobile environments.
Hence, based on our study, Distributed Neighborhood Discovery
Protocol (DNDP) is proposed that can make online decisions to
find the best transmit power and frequency for sending discovery
packets so to minimize the effect on routing.},
