4G technology is meant to provide what is known as “ultra- broadband” access for mobile devices. LTE advanced, was submitted as a candidate for the 4G system to ITU-T (ITU Telecommunication Standardization Sector) in 2009. It was approved into IMT Advanced and was finalized by the 3rd Generation Partnership Project (3GPP) as a major enhancement of the Long Term Evolution (LTE) standard in March 2011[1].
In [2] an overview of the current state of standardization efforts in M2M communication is given. Lien et al. [3] provide an overview of the network architecture and features of M2M communications in 3GPP, and identify potential issues including physical layer transmissions, the random access procedure, and radio resources allocation. They also propose a solution to provide QoS guarantees to facilitate M2M applications with hard timing constraints. In [4] a Mobility architecture, IoMANETS, is proposed for Wireless M2M networks. The design provides a fault tolerant solution to the mobility issue by allowing mobile nodes to seamlessly connect to M2M-Internet of Things infrastructure. The assumptions are that fixed nodes are connected to the internet with either IPv4 or IPv6 and the mobile nodes have IEEE
802.15.4 adapters operating a 6LowPAN IP stack. IoMANETs facilitates the reachability of the device using indirections based on the original global address. Our approach was not focused on fault tolerant connectivity of mobile nodes but was rather on QoS issues in connecting WSN to 4G devices.
Probably the work that is most similar to ours was proposed by Zhang et al. [5]. In their work they examined network
