Abstract
Wireless sensor networks apply to different topologies. A particular case is a linear topology included in monitoring large-scale linear infrastructures. Linear topology requirements differ from other topologies. The architectures and protocols for wireless sensor networks are references modified depending on the application. These architectures and protocols are complex if applied to linear topologies with thousands of nodes. This paper discusses the existing standards and protocols applicable to linear wireless sensor networks, defines their particular characteristics, and how current protocols can satisfy the requirements of networks with linear topology. The information related to linear Wireless sensor networks, medium access control, routing, transport, and the specific needs of this type of network is presented. Finally, the challenges for the existing protocols and some challenges to the new protocol's design of linear topology are identified.
