Efficient Route Update and Maintenance for Reliable Routing in Large -Scale Sensor Networks
Abstract:
Reliable data transmissions are challenging in industrial wireless sensor networks as channel
conditions change over time. Rapid changes in channel conditions require accurate
estimation of the routing path performance and timely update of the routing information.
However, this is not well fulfilled in existing routing approaches. Addressing this problem, this
paper presents combined global and local update processes for efficient route update and
maintenance, and incorporates them with a hierarchical proactive routing framework. While
the global process updates the routing path with a relatively long period, the local process
with a shorter period checks potential routing path problems. A theoretical modeling is
developed to describe the processes. Through simulations, the presented approach is shown
to reduce end-to-end delay up to 30 times for large networks, while improving packet
reception ratio (PRR) in comparison with hierarchical and proactive routing protocols
ROL/NDC, DSDV, and DSDV with IPv6 Routing Protocol for Low-Power and Lossy Networks'
Trickle algorithm. Compared with reactive routing protocols AODV and Ad Hoc On-demand
Multipath Distance Vector, it provides similar PRR while reducing end-to-end delay over 15
times.
