The Internet of Things (IoT) is the concept of everyday objects that make us live in the era of the IoT. The spatial characteristics of things around us can be considered the reins of the IoT operability. In other words, the spatial variation of a thing can be the core of the IoT reaction. For example, the spatial variation in crop indicates the requirement and characteristic of agriculture production. Also, the spatial variation of a human movement can alarm the security and monitoring systems. This issue agitates the contemplating of the ''Internet of Spatial Things (IoST)'' concept. For the first time, this paper draws an inspiration towards the perspective vision of the IoST, which is concerned with revise IoT with the spatial perspective. The IoST concept is argued by the presentation of its definition and architectural components. Besides, the IoST layers are discussed in details. Furthermore, a new proposed reference model of the IoST is proposed. Finally, the new trends and open issues regarding the IoST are aroused.

In this paper we develop a Directional Antenna Multi-path Location Aided Routing (DA-MLAR) scheme with On Demand Transmission Power (ODTP) support. The routing approach is based on multiple objectives. DAMLAR is a reactive routing protocol that minimizes the protocol overhead of other reactive routing protocols. DAMLAR also improves the packet delivery ratio and end-toend delay. The targeted application contexts include MANET with energy awareness, and communications in space networks, where efficient and reliable packet delivery is very challenging due to the high bit error rate, intermittent connectivity, limited bandwidth, and energy. By using different transmission power based on the calculated distance from the current sender node to the destination node or the next hop node, DA-MLAR-ODTP gets the best of the directional and omni-directional modes. Compared to DA-MLAR, on demand transmission power mode further improves the packet delivery ratio by up to 37% and dwindles end-to-end delay by up to 57% with approximately the same amount of energy consumption. The multiple objective optimization is based on using a Normalized Weighted Additive Utility Function (NWAUF) approach that shows comparison of different objective performances with and without on demand transmission power capability. Simulation experiments were conducted. They show that is the developed technique strengthens the reliability of communication systems for given targeted objectives.

This paper studies a Directional Antenna Multi-pathLocation Aided Routing (DA-MLAR) scheme with on demand transmission power support. The targeted application contexts include communications in space networks, where efficient and reliable packet delivery is very challenging due to the high bit error rate, intermittent connectivity, limited bandwidth and energy. This research enhances our DA-MLAR protocol with On Demand Transmission Power (ODTP) capability. By using different transmission power based on the calculated distance from the current sender node to the destination node or the next hop node, DA-MLAR-ODTP gets the best of the directional and omni-directional modes. Compared to DA-MLAR, on demand transmission power mode further improves the packet delivery ratio by up to 37% and dwindles end-to-end delay by up to 57% with more or less the same amount of energy consumption. Simulation experiments show that this is a promising technique for more reliable communications in MANET with energy and other constraints.
