Title
The Effect of Transmission Range in Multi-hop Wireless Networks

Abstract
Transmission or communication range is an important
factor for successful data delivery in wireless communications
including multi-hop wireless networks. Typically, transmission
range can be technically adjustable by configuring the transmitting
power (Tx Power) or changing the antenna height. For
the same antenna height, if transmission range is minimized
or adjusted to be shorter by lowering Tx power, there is less
energy consumption but the networks are likely to be unconnected
which consequently degrades the network performance such as
throughput and delivery ratio. In the case that range of nodes
is maximized or extended for connectivity by increasing Tx
power, networks become connected and a node may reach the
others by using just a hop. This beneficially affects network
performance but these nodes with range extension consume more
energy for data transmission. Hence, there is trade-off between
energy consumption and network performance when adjusting
transmission range. In addition, in multi-hop wireless networks
where nodes are usually mobile and network topology are highly
dynamic, transmission range has lots of impact on network
performance. Hence, to study the effect of transmission range
is very important and required. In this work, various scenarios
(i.e. load-, speed- and density-varying scenarios) are constructed
to investigate both energy consumption and network performance
with different transmission ranges.
