3.2Development of evaluation equipmentWe have developed the evaluation equipment with an aim to comprehensively evaluate the L2R control functions described in Section 2. Figure 7 shows the appearance of the evaluation equipment. is study evaluated the operat-ing characteristics for the building and operation of the mesh structure by the MAC layer control as described above on PAN which is composed of two devices, which have the mesh route functions, and ten non-mesh route devices. Figure 8 shows an action indication example of the multiple services supporting function among the previ-ously mentioned functions. is action diagrammatically presents the Layer 2 Mesh structure like Fig. 2 in which the mesh structures are respectively dierent due to two mesh routes within the same PAN. In addition, Fig 8 shows that some devices (B, C, F, G, I and J) take part in the mesh structures which any mesh roots dene, and contribute to both routing.3.3Implementation of evaluation testTo evaluate the L2R control function, we have con-ducted data collection experiments in indoor and outdoor environments using the evaluation equipment in the above subsection. e experiments were conducted around the National Institute of Information and Communications Technology (NICT), Yokosuka City in Kanagawa prefec-ture. Figure 9 shows the layouts of two mesh structures to evaluate the operating characteristics of the multiple ser-vices supporting function as Figs. (a) and (b), respectively.
