Wireless Sensor Networks (WSNs) are networks of small, cheap, independent battery-powered sensor nodes, finds applications in agriculture, health care, intrusion detection, asset tracking, habitat monitoring and in many other fields. It is sometimes necessary to disseminate data via wireless links after the deployment of sensors so as achieve the objectives of sensors configurations parameters adjustment or distribution of commands management and queries to sensors. The present study considered how Shortest Path Minded Sensor Protocols for Information via Negotiation (SPIN)-Recursive (SPMS-Rec), reduces the energy dissipated in the event of failures by requiring intermediate relay nodes to try alternate routes, is suitable for data dissemination. Despite to the power constraints and memory limitations of sensory nodes, ‘Instantly Decodable Network coding’ (IDNC) was considered because of its practicality, relevance and numerous desirable properties such as instant packet recovery, simple XOR-based packet encoding and decoding, and zero buffer memory to store un-decoded packets. The paper concludes with reference and suggestions of possible future research areas. |
