During the past decades, we have witnessed significant research and development efforts related to Sensor Networks (SN) with both wired and wireless technologies. Those efforts resulted in the development of benchmark application paradigms for SNs with applications in both safety-critical and non-safety-critical fields, including environmental monitoring, military apps, tactics, smart sensing, underwater sensing, pollution sensing, fire alarms, and other hundreds of applications to improve our lifestyles. Similarly, the Internet of Things (IoT) has been promoting the emergence of various networking technologies with standardization efforts being carried out by the IEEE community. SNs have been proven to be the most investigated topic for enabling IoT applications. For example, sensors installed in a house may update the owner on his/her cell phone about any medical or security threat. However, to support such applications, SNs and IoT come up against several constraints, like low capacity processing capabilities, battery operated devices, limited transmission ranges, and limited data transmission capacity. One of the key issues in IoT and SNs is the efficient data forwarding in terms of energy consumption, multi-hop data retrieval, safety/emergency message dissemination, etc. The goal of this special issue is to present and highlight the novel advances, emerging technologies, and applications targeting the efficient data collection is the internet of things and sensor networks. This special issue contains thirteen regular papers which can be organized into three groups: data forwarding in SNs, energy efficiency in wireless body area networks, secure data forwarding in SNs.
