Modified source-routing for large-scale pseudo-linear ZigBee networks

ZigBee devices are resource-constrained. So, they cannot run traditional heavyweight routing algorithms. Although, ZigBee proposed a table-free, simple routing algorithm for tree networks, it does not support long linear networks typically set up in roadside, mines, agricultural field, mountains etc In this paper, we have proposed a light-weight routing algorithm based on source routing that supports arbitrary long networks. The proposed algorithm is especially suitable for networks that look almost linear. The algorithm leverages the properties that a pseudo-linear network has limited branching. Experimental results show that this flexible mechanism exhibits excellent packet delivery performance.
