Source-Initiated Routing to Support Large-Scale Pseudo-Linear ZigBee Networks

IEEE 802.15.4 compatible instruments are resource-limited; thereby cannot run conventional resource-hungry routing algorithms. Even though, ZigBee supplied a simple routing algorithm for tree networks, it cannot handle long linear networks typically set up in mines, roadside, agricultural field, mountains etc. his paper proposes a light-weight routing logic 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.
