- Virtual position-based routing protocols have many
attractive characteristics for wireless sensor networks. Typically,
such protocols use a proactive scheme for updating routing tables.
Because sensor networks can have very low data rate, sending
periodic beacons to update routing tables can be very expensive.
Instead, reactive approaches might be more appropriate in such
scenarios. MANET-inspired reactive routing protocols do not
scale well because of the effort in the order of O(n) for each
routing information update. In this paper, we present Reactive
Virtual Cord Protocol (RVCP), a data-centric reactive virtual
position based routing protocol for use in sensor networks. Route
discovery is directed towards the destination and hence there is
no need to flood the entire network to discover a route. Our
approach is based on Virtual Cord Protocol (VCP), an efficient,
virtual relative position based routing protocol that also provides
support for data management as known from typical Distributed
Hash Table (DHT) services. To minimize the end-to-end delay
and energy consumption, we used adaptive techniques for the
development of RVCP.
