Reliability In Wireless Sensor Networks By Multipath Routing Of Encoded Data
A new technique of data encoding and multipath routing in a wireless sensor network is described. The data is
encoded into L shares (packets). These L shares are transmitted over L different node-disjoint paths to the destination. At the
destination, any T packets are sufficient to recover the data where T < L. This is T out of L threshold encryption/decryption
scheme. This scheme can tolerate up to (L – T) packet losses. Thus provides good data reliability. Because of encryption
involved in creating the shares, the proposed scheme also provides some degree of security.
