A SURVEY ON MULTIPATH ROUTING STRATEGY IN MULTI-HOP WIRELESS SENSOR NETWORK

There are number of routing protocols proposed for the data transmission in WSN. Initially single path routing schemes with number of variations are proposed. Sti ll there were some drawbacks in single path routing . Single path routing was unable to provide the reliability and h igh throughput. Also security level was not conside red while routing. Recently,to remove the drawbacks of the s ingle path routing new routing technique is propose d called as multipath routing. In this paper we discussed the different multipath routing protocols with number of variants. Initiall y multipath routing was proposed for the purpose of guaranteed delivery of packet to sink in case of link or node failure. There are other protocols which are proposed for the reli ability,energy saving,security and high throughpu t. Some multipath routing protocols have discussed the load balancing and security during packet transmission. https://www.ijiert.org/paper-details?paper_id=14037
