Abstract Wireless sensor network (WSNs) has potential to solve the problem automatically with less or no human intervention in most of the cases. Time constraint event (TCE) and non-time constraint (NTCE) event are two broad categories in heterogeneous WSNs. To address the QoS parameters in TCE and nTCE type of applications are crucial job in resource constraint multi-event WSNs. The queue scheduler performs those set of actions which are necessary to achieve the desired QoS parameters for each distinct event separately in a sensor network. A study mainly focuses on priority-based reliability with considering their different levels of priority of traffic. Decisions are taken at various intermediate nodes by managing queue. For each level of priority a separate queue is maintained. Queue management is the heart of proposed priority architecture for achieving quality of services. Due to proper queuing operation, scheduler takes the right decision at right time to attain the required reliability. Scheduler accomplishes desired goals of every application by handling their priority and deadlines.

1 Introduction Nowadays, wireless sensor network [1–3] is growing rapidly in the Internet of Things (IoT) world. Contributions of sensor technologies are reflected in almost every field. Wireless technologies such as ZigBee (802.15.4), Wi-Fi (802.11), and Bluetooth are mainly used. Mainly ZigBee wireless technology is used as it consumes less energy compared to other technologies. There are many challenges in WSNs [4–7] because of having minimum energy, memory, and processing capability. In case of heterogeneous WSNs, there are more challenges as it deals with different types of traffic at a time. Handling various traffic with or without priority are challenging tasks. Making a generic protocol in WSNs is very difficult job because of having distinct QoS requirements of each one separately. The structural design model shows the operation like classification of information, storing information in respective queue, rate-based packet scheduler, and delay-based packet scheduler as shown in Fig. 1. RF-based transceiver transfers or receives data wirelessly.
