Greedy Based Single Path & Multi Path Protocol for Wireless Sensor Networks?

Many latest equipments uses Wireless Sensor Networks (WSNs) to monitor physical or environmental conditions but there is huge scope for node failures due to energy constraints or due to tendency of a wireless networks which is as that of a vector where nodes can be added or removed from the network upon the request of application due to which network can’t stick to a specific topology. The scope of a wireless sensor node is very limited with respected to transmission range of wireless sensor nodes due to which multiple hops are needed for a node to exchange information with other nodes. A multipath routing scheme is used to distribute the network traffic across multiple paths instead of routing all the traffic towards a single path by which the consumption of energy will be splitted among multiple nodes within a network resulting in longer lifetime of a datagram and hence it provides better quality of service. In this paper, we propose a energy efficient multipath routing protocol that uses the 1) reusable energy that can be transmitted to other node while performing hopping, 2)the available buffer size of a node or a router, 3) handling of Signal to Noise Ratio that is used to predict the finest next hop through the paths construction phase, our proposed system examines two methods of traffic allocation where the first method uses a single path among all the possible available paths to transfer the data message when the path cost is below a specific threshold value based on which alternative path is selected then the datagram is transmitted and the second method is to split up the transmitted message into number of segments of equal size based on error correction codes and then transmit it across multiple paths simultaneously where a datagram is received at the destination node without sustaining excessive delay.
