Machine Type Communication (MTC) is a key component of future 5G networks, and its realization is now possible due to the advances in technology and the market drivers. Several challenges however exist which hinder the realization of MTC, among which signaling overhead is considered the prominent challenge, particularly due to the massive number of devices in MTC networks. In this work, we consider...
In order to accommodate the exponentially-growing data traffic, LTE operators are considering the extension of the LTE operation into the unlicensed bands. In a recent technical report for the third Generation Partnership Project, Licensed-Assisted Access (LAA) to the unlicensed spectrum has been introduced. The report and other works in the literature reveal coexistence challenges that are raised...
This work proposes a replication scheme that is implemented on top of a previously proposed system for MANETs that cache submitted queries in special nodes, called query directories, and uses them to locate the data (responses) that are stored in the nodes that first request them, called caching nodes. The system, which was named distributed cache invalidation method (DCIM), includes client‐based...
