Wireless Machine-to-Machine Routing Protocol with Unidirectional Links
Megat F. Zuhairi · The Smart Computing Review · 2011
Wireless Machine-to-Machine (M2M) technology is a new approach to network communication that covers a wide area of applications. In this paper, we propose a reliable on-demand routing protocol for wireless M2M in Mobile Ad Hoc Network (MANET) applications such as telematics, healthcare devices, remote sensing for data mining, and building security monitoring systems. Generally, devices in such networks are typically battery powered and have wireless interfaces that could be connected to existing wireless infrastructures (e.g., IEEE 802.11) wireless networks. Devices on the network have different properties (i.e., transmission power) and thus communication may follow a sub-optimal path (i.e., asymmetrical path). We propose a reliable routing protocol that efficiently constructs a routing path in M2M with minimal route acquisition time and is capable of utilizing all possible link connectivity (i.e., unidirectional and bidirectional links). The performance differentials are investigated using NS-2. Our simulation results show that the proposed scheme achieves minimal end-to-end delay connection, higher goodput, and maximum reduction of normalized routing loads when compared with the competing Ad Hoc On-demand Distance Vector (AODV) routing protocol.
