摘要：To make Internet of Things Platform lightweight,there is need of lightweight software and hardwarecomponents. CoAP(Constrained Application Protocol) is lowpower consumption and low energy communication protocolfor constrained environment. We built the lightweight IoTplatform using CoAP. We also enhance the platform withCoAP Block-wise transfer feature. Sometimes applicationsneed to transfer larger payload than the payload that fits intosingle message. This type of data slicing is handled well atapplication level than lower level ( e.g. IP layer or adaptationlayer). In CoAP, Block1 and Block2 options are provided fortransferring request payload and response payloadrespectively in block-wise fashion. The lightweight IoTplatform is built using Node.js. We implement Block1 featurefor node-coap library which is CoAP implementation forNode.js.
