While the sharing algorithm is running, Header node may want its own resources.
but as programming issue, Header node can not get them.
below is the problem code.
there are no function that header node gets the resources.

/**
     * get Resource from Header Node
     * @param requestdata
     * @param resHandle 
     */
    private void getResource(SendMessage requestdata, ResponseHandler resHandle){
        if(!isActivated)
            return;
        
        if(routingprotocol.isHeaderNode()){
            //get child node resource -> use other method in here
        }else{
            Node header = routingprotocol.getHeaderNodeofCurrentNode();
            requestdata.AddAttribute(Request.MSG_ATTR.Sharing, SharingMessage.CLIENT_REQUEST.getValue());
            frame.REQUEST_GET(header.gettoAddr(), requestdata, resHandle);
        }
    }

CoAP Requirement - CoAPPacket.java
Option

• MAX-AGE
• Content-format

Payload

• message format : JSON type
• Basically, CoAP protocol payload in MinT includes MinT protocol like (source, final destination)
• All IoT devices which are included in whether MinT or other middleware must communicate each other with CoAP protocol.
• MinT do not use CoAP attribute. it need to use CoAP attribute.

OS에 IPv6와 IPv4를 동시에 사용하는 네트워크 인터페이스가 있을 시 발생할 수 있는 오류
기본적으로 Java는 IPv6정보를 받아오기 때문에 수정 해 줄 필요가 있음

It occurs in OSs which use the IPv6 and IPv4 such as Linux based.
Basically, Java uses the IPv6 network in OS.

Add option below

java -Djava.net.preferIPv4Stack=true

• Target node need to response ACK message, if it receives the message which doesn't need the response message.
