“…Thus, 1 leads to availability and 0 leads to the occupancy of an IP address. The selection process is as follows: The node generates a random integer in the interval [1,4]. In the example below, the selected number is three.…”

“…Management of these applications running on various types of consumer devices in one network is a challenging problem. Therefore, a heterogeneous architecture consolidating different operating systems and communication protocols such as Bluetooth, ZigBee, and the traditional IP networks seems to be emergent [1][2][3]. Normally, in IP networks, each electronic device behind a network address translation (NAT) is assigned a private IP address by the corresponding service provider [4].…”

SUMMARYIn this article, we propose a dynamic Internet Protocol (IP) address assignment architecture for heterogeneous wireless IP devices network. The IP device could be a sensor device, a laptop, a cell phone, or any wireless device using IP communications. The proposed architecture introduces security and service reliability to the consumer while reducing the operational expenditure for the service providers. According to the proposed scheme, each node maintains an IP address pool storing the current occupancy of each IP address. Each node advertises its database whenever the ratio of negative acknowledgments from the domain name server to the total number of requests at a given node exceeds a certain threshold. We evaluate our IP assignment scheme under two traffic intensity scenarios, namely the uniform traffic intensity and the heterogeneous traffic intensity. Performance evaluation is carried out with respect to blocking probability and average IP list utilization. We define three types of blocking probability for the user requests as follows: The real blocking, the unjustified acceptance, and the unjustified rejection. We observe that the proposed scheme outperforms the uniform assignment as long as the threshold is below 1.5% for the uniform intensity scenario and 1% for the heterogeneous scenario. Furthermore, this architecture considers the security aspect of the wireless network by allowing only registered devices to communicate with other registered devices. Copyright

“…Successful operation of a multihop protocol requires self organizing cluster formation, autonomous CH selection, and an energy-efficient MAC. Multihop synchronization, cluster formation, and CH election techniques have been addressed in many research works [10,3,[12][13][14][15][16][17]. In [10], the authors have presented the RT-Link protocol, which provides a multihop synchronization scheme.…”

“…In [14], the authors introduced a technique of application-aware radio duty cycling called on-demand spatial TDMA for a moderate-scale network. In [15], an ultra-low duty cycle SCP-MAC was proposed. The SCP-MAC has shown better performance in energy saving than the existing MAC protocols such as S-MAC, T-MAC, B-MAC, and WiseMAC.…”

SUMMARYThe IEEE 802.15.4K Task Group was formed recently to address the low energy critical infrastructure monitoring networks. The aim is to collect scheduled and event data from a large number of non-mains powered endpoints that are widely dispersed. The application requirements include reliable data transfer, energy efficiency, and long deployment lifetime. To meet the low energy critical infrastructure monitoring network requirements, we propose a multihop medium access control protocol where the scheduled or event data are routed to the coordinator through the cluster heads. The power consumption of the cluster heads is critical as they use more power than the normal endpoints. Our protocol uses the wake-up radio approach from cluster head to cluster head communication and an efficient guaranteed time slots allocation scheme to minimize the power consumption of the cluster heads. We derive analytical expressions for the average power consumption of cluster heads as well as ordinary endpoints. The results show that our proposed protocol outperforms the IEEE 802.15.4 MAC and SCP MAC in terms of power consumption. High power efficiency is achieved in both the cluster heads and normal endpoints.

“…The Wireless Sensor Network [1,2,3] is of this type of network. In the wireless sensor network, besides two important issues, the sensor coverage [4,5] and the network connectivity [6,7] are closely related to the sensing range and the effect of data delivery, the efficiency and reliability of data broadcast transmission are also important research subjects. As the wireless network has lower data rate and higher bit error ratio, as compared with the wired network, and the wireless devices in the wireless sensor network have the task of packet forwarding and must execute routing protocol related operation, if a favorable algorithm is not used in data broadcast, the network overhead will be increased, and the efficiency and reliability of the network will be decreased.…”

Abstract-As we know, the data transmission in the wireless networks is more unreliable than it is in the wired network environment. Although the virtual carrier sensing scheme can be used in the wireless unicast transmission, the multicast and broadcast still not utilize the acknowledgement mechanism for reliable transmission. This is due to the acknowledgement packets of broadcast transmission will cause much higher communication traffic and overhead. Since reliable data broadcast is critical and required in many applications in the wireless sensor networks, our study focuses on the ZigBee network which is a new industrial standard for sensor networks. Some previous related papers improved the broadcast reliability by introducing redundant transmission and increasing coverage ratio of every receiver node, but there still exists probability of packet loss and extra communication cost due to redundant broadcast. This paper proposes an efficient acknowledgement-based approach for reliable data broadcast in wireless sensor networks. Hierarchical acknowledgement mechanism, reduction of rebroadcast packets and ACK packets, degree-based ACK/rebroadcast Jitter, and parent-oriented retransmission are the key schemes to achieve the efficient data broadcast. Simulation results show that the proposed schemes can efficiently reduce the acknowledgement traffic as well as communication overhead and provide the high reliable data broadcast transmission in ZigBee networks..
