Summary: | 碩士 === 國立交通大學 === 電控工程研究所 === 101 === An ad-hoc network, constructed by a set of mobile nodes, is a
decentralized small wireless network and does not require any
infrastructure or the central control systems.
Each mobile node in this network can either send/receive messages or
help relay messages in between.
This has brought up a need of an efficient routing protocol which can
route packets between mobile nodes.
Zone Routing Protocol (ZRP), as one of the ad-hoc routing protocols,
creates a topological map of a zone for routing packets, such that the
whole ad-hoc network can benefit from the local topology information
of the entire zone.
In this thesis, we propose a ZRP-based routing protocol to dynamically
adjust the zone size by the node mobility while reducing the overall
routing cost of an ad-hoc network.
We also consider the residual energy of each node on a routing path
and select the path with maximum residual energy to increase the
network lifetime.
Through some simulations, we compare the proposed protocol with ZRP in
terms of message delivery latency and energy consumption.
The results show that our protocol has improved the latency by a
factor of 34.68 for a low-mobility network. In addition, our protocol
can consume energy more evenly on every relay node than ZRP.
