Design of A Minimal Control Traffic Overhead Topology Discovery and Data
Forwarding Protocol for SDWSNS
Efficient Topology discovery and maintenance are the most critical
requirements of Software Defined Wireless Sensor Networks (SDWSN).
Existing SDWSN protocols for discovering the underlying network topology
put more constraints on the already limited wireless sensor node
resources. Previously, an extensive literature survey was conducted and
this fact was established. In this paper, a novel minimal control
overhead topology discovery and data forwarding protocol is proposed and
detailed. The proposed protocol requires some changes to the topology
discovery protocol implemented in SDN WISE to improve its performance.
The proposed protocol has been implemented in the IT-SDN framework for
evaluation. The results show reduced control packet overhead and
improved energy consumption compared to the existing protocol. Besides,
the implementation shows an increase of 20% data packet delivery rate
over the protocol in SDN WISE.
